INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD The present invention relates to a sensing element and a power sensing device using the same, and in particular, the invention relates to an electrical property by air bubble plastic A sensing element and a power sensing device using the sensing element. [Prior Art] In the microstructure, especially in the biochemical detection, the fluid-filled microchannel, the internal bubble is very different from the surrounding medium due to its nature. Therefore, the position of the bubble and the bubble generation process can be used as different Applications. For example, U.S. Patent No. 4,175,289 discloses the use of different locations of magnetic bubbles as a data storage device similar to the 0/1 read state. Another ^ = special, said 7592 and the 7th let the 74th _ _ a kind of communication Μ bubble and the surrounding environment refractive index difference as an optical switch. The above prior art uses the position of the bubble as its application. In addition, fluid jets are used in Fluid Confucianism such as Charm or Bubble Pumps. Correction of rolling and fortune detection should be like: Line:: Disease π see biochemical biochemical or medical testing instrument "It is used to live in household electricity or power generation equipment as its power source, and live electrical appliances can not function properly However, a small biochemical or medical testing instrument is insufficiently charged. 201006434 [Invention] Therefore, one aspect of the present invention is to provide a sensing element. The above problem is solved by the use of a bubble to influence electrical characteristics and to sense a change thereof to generate a sensing signal. According to a specific embodiment, the sensing element of the present invention comprises a flow path, a bubble generator and a sensor. To accommodate the fluid, the bubble generator and the sensor are disposed on the inner wall of the flow channel. In this embodiment, the bubble generator can be coupled to the power source to receive the power provided by the power source to generate at least one bubble, and sense The device is used to sense the electrical characteristics around it and generate a sensing signal. When the bubble generated by the bubble generator approaches the sensor, the bubble will affect the electrical characteristics around the sensor. The sensor can adjust the sensing signal according to the change of the electrical characteristics. According to another specific embodiment, the sensor of the above specific embodiment may further comprise a first electrode and a second electrode connected to each other in opposite polarity, and the fluid thereof $ electrolyte. When the first electrode and the second electrode receive i power supplied by the power source, the first electrode and the second electrode can electrolyze the fluid to generate bubbles. Another scope of the present invention is to provide a power sensing device that can be used. The power sensing device of the present invention includes the sensing element tf, the second sensing element further includes a flow channel, a bubble generator, and a sensor. The flow channel is used to The accommodating fluid, the bubble generator and the sensor are disposed on the inner wall of the flow channel. In this embodiment, the bubble generator can be coupled to the power of an electronic device to receive the power provided by the power source to generate at least one Bubbles, and the sensor is used to sense the electrical characteristics around it and generate a sensing signal accordingly. When the bubble is generated by the bubble 201006434 bubble generator When approaching the sensor, the bubble will signal, the electrical characteristics, and the sense n can be adjusted according to the change of the electrical characteristics. The specific bubble generator of the embodiment is based on the power of the power source. For example, if the power supply / Λ, the bubble generator can produce larger bubbles or more bubbles, the electrical characteristics around the sensor change is also greater. The other side of the battery When it is insufficient, the bubble generator can generate a small bubble J/gas bubble, and the amount of change in the electrical characteristics around the sensor is also smaller than the change of the test signal, which can be used to determine whether the power supply of the electronic device is sufficient. The advantages and spirit of the present invention can be further understood by the following figures. & s Secrets and Embodiments [Embodiment] Referring to Figure 1, Figure 1 shows a test according to the present invention. 1 of. schematic diagram. As shown in Figure -, the sensing element gas/package generation state 12 and sensor 14 are shown. Wherein, in the flow channel power source, the bubble generator 12 can be coupled to the power source port to receive at least one bubble 1〇2. Please note that in practice, it is possible to sense 70 built-in power supplies, or to provide power for another electronic F, depending on the needs of the user or the designer. The electronic device produces a show-recording, but the secret shot is based on the bubble. The column can be sized according to the size of the power it touches. For example, if the bubble generator 12 receives power to generate a blister W2, the (four) connection (four) force magnitude can be used to control the number of bubbles 1 〇 2 corresponding to the number of halos. On the other hand, if the bubble generator 1; 2 receives power to generate a bubble 102, it can generate a small bubble 102 depending on the magnitude of the received power. In addition, the sensor 14 further includes a first sensing unit 14A, a first measuring unit 142, and a processing unit 144. The first sensing unit 14A and the sensing unit 142 are disposed on the inner wall of the flow channel 1G. It is also possible to make electricity between the two and the surrounding area. The omnidirectional unit m generates a sensing signal according to electrical. Please note that in practice, the processing unit 144 of the sensor M can be placed in the flow channel 10 or outside the flow channel 10 without being limited to the specific embodiments listed in this specification. When the bubble generator 12 generates the bubble 1〇2 and the bubble 1〇2 is close to the sensor 14 to affect the electrical characteristics around it, the sensing signal generated by the sensor 14 will vary with electrical characteristics. In addition, in practice, the position of the sensor 14 can also be adjusted according to the needs of the user or the designer, and is not limited to the specific embodiment. For example, the first sensing unit 14 〇 and the second sensing unit 142 can also be respectively disposed on both sides of the bubble generator 12 , and directly affect the first sensing unit 14 when the bubble generator 12 generates the bubble 102 .电气 and electrical characteristics between the second g measuring unit 142. ~ 流体 The fluid 100 of the present embodiment may have electrical conductivity, and since the bubble generator 12 generates a corresponding size or number of bubbles 102 according to the magnitude of the received power, the power received by the bubble generator 12 is relatively large. When it generates a larger or larger number of bubbles 1 〇 2 and affects the electrical characteristics around the sensor μ to a greater extent, the sensing signal changes greatly; on the other hand, when the bubble generator 12 receives power In hours, it produces less or less bubbles 1〇2 and affects the electrical characteristics around the sensor 14 to a lesser extent, resulting in less variation in the sense signal. See Figure 2 for the sake of clarity. Figure 2 shows the sense of the sensing element i in Figure 1. The time domain of the test signal. As shown in Figure 2, the horizontal axis is the time 感 sense signal strength γ. The bubble generated by the _ segment a and the time f and the vertical axis is the generator 12 does not affect the sensor i = bubble production (or bubble generation H 12 has not yet moved to the bubble), and the characteristic ^S S generator 12 The generated bubble 1〇2 influences the sensor. When the power received by the bubble generator 12 is large, the bubble 102 that is large or eve is affected and affects the periphery of the sensor 14.

On the other hand, if the power received by the bubble generator 12 is small, the air bubbles 102 having a straight or peak peak or less affect the electrical characteristics around the sensor 14, resulting in a small change in the sensing signal. Referring to FIG. 3, FIG. 3 is a schematic diagram showing the sensing element 1 according to another embodiment of the present invention. As shown in FIG. 3, the specific embodiment differs from the previous embodiment in that the bubble generator 12 of the sensing element of the specific embodiment further includes a first electrode 120 and a second electrode 122. Additionally, fluid 100 can be an electrolyte, such as water, in this particular embodiment. In the present embodiment, when the bubble generator 12 receives the power of the power source ρ, the first electrode 120 and the second electrode 122 can supply charges of different polarities to electrolyze the fluid, thereby generating bubbles of different internal gases. 2 and 102'. For example, if the fluid 1 is water, the first electrode 120 provides a positive charge and the second electrode 122 provides a negative charge, the fluid 100 is electrolyzed by the first electrode 120 and the second electrode 122 at the first electrode 120. A bubble 102 in which the internal gas is oxygen is generated, and a bubble 102' in which the internal gas is helium is generated at the second electrode 122. Similarly, when the bubble 102, 102' and the fusion bubble of the two affect the electrical characteristics between the first sensing unit 140 and the second sensing unit 142 of 201006434, the sensor 14 is adjusted according to the change of its electrical characteristics. Sensing signal. In the present embodiment, since the bubbles 102, 102 are formed by the electrolytic fluid 100, when the two are fused into a fused bubble, the two gases in the fused bubble are reduced to the fluid 100. Depending on the type of fluid 100, the gas in the bubbles 102, 102' and the rate at which the two gases are reduced to the fluid 100 are also the same. In practice, the catalyst may be placed in the flow channel 10 to catalyze the reduction of the two gases in the fused gas into a fluid (1) depending on the needs of the user or designer. "Melon φ as described above" because the bubbles 102, 102 of the present embodiment can be fused to each other and the gas between them can be relocated to the fluid 100, and therefore, when the bubble generation state 12 is performed, the bubbles 102, 102' are again generated. When measuring the characteristics of the gas around the sensor 14, it is not caused by the bubble generated last time remaining in the sensor 14 and the sensor 14 is misjudged. However, the rate of the right gas is slower. In practice, the inner wall of the flow channel 10 can be designed with different roughness. When the middle of the fusion bubble is degraded into the fluid 100, the space occupied by the fluid 100 backfilled from different directions is rough according to the inner wall of the flow channel 10. Degrees and different rates, this reference will generate a resultant force for the fusion bubble that has not been reduced to fluid 1 (8) to push the fusion gas. By the inner wall roughness design of the flow channel 10, the fusion bubble can be pushed away from the sensor 14 The situation in which the above-mentioned residual air bubbles cause the sensor 14 to be misjudged is avoided. Note that in practice, the inner wall roughness design of the flow path 10 can also be directly formed by the arrangement of the sensor 14 or the bubble generator 12. ~ See the figure Figure 4 is a schematic view showing a sensing element 1 according to another embodiment of the present invention. As shown in Figure 4, the difference between the specific embodiment and the above specific embodiment lies in the flow path of the specific embodiment. 10 has two bevel structures 104 respectively disposed adjacent to the sensor 14. In addition, the flow channel 1 further includes two waterproof gas permeable structures 106 adjacent to the two bevel structures 1〇4. 201006434 In the present embodiment, 'bubble l〇 2 close to the sensor 14 can be guided by the bevel structure 104 to approach the waterproof gas permeable structure 100, then the bubble 102 can reach the position of the waterproof gas permeable structure 106 and leave the flow channel 10 through the waterproof gas permeable structure to avoid residual bubbles causing the sensor 14 The situation of misjudgment. In practical applications, 'various measuring instruments are inevitably subject to noise interference. Similarly, noise may interfere with the sensing signals generated by the sensors of the sensing elements of the present invention, especially When the amplitude of the sensing signal is not large, the influence of the noise will be more significant. 凊 凊 阅 五 五 , , , , , , , , , , , , 示意 示意 示意 示意 示意 示意 示意 示意 示意 示意 示意As shown in FIG. 5, the sensing element 2 has a flow channel 2, a bubble generator 22 and a sensor 24, wherein the flow channel 2 can accommodate the fluid 2, the bubble generator 22 and the sensor 24 can It is disposed on the inner wall of the flow channel 20. The bubble generator 22 can generate the bubble 20^' according to the power supplied from the power source P1 and affect the electrical characteristics around the sensor 24 when the bubble 202 is close to the sensor 24. The sensor 24 can Sensing the electrical characteristics around it and generating the sensing signal S1. In the specific embodiment, the sensing element 2 further comprises a first reference element 4 and a second reference element 28. The first reference element % also has The channel and the sensing H placed in the flow channel, the flow channel can accommodate the same gas as the bubble generator gas component, and the sensor can sense the surrounding electrical characteristics and generate the first reference signal accordingly. C1. In addition, the second component 28 has a flow path and is disposed in the reducer; it accommodates the fluid 200, and its sensor can sense the 3-gas characteristic and generate a second reference 峨C2. It is noted that the second t of the present embodiment can also be disposed in the flow path 2〇, but the bubble 202 generated by the bubble generator 22 does not affect the second reference element 28. 11 201006434 The sensor 24 and the first reference component 26 can be coupled to the first differentiator 3 〇 to input the sensing signal S1 and the first reference signal ci into the first differentiator 3 〇, and the sensor 24 and the first reference The component 28 can be connected to the second differentiator 32 to input the second differentiator 32 with the additional word sensing signal S1 and the second reference signal C2. The first differencer 30 can obtain the first difference 〇1 according to the sensing signal S1 and the first reference signal C1 and input the first one by using the operation of the first differencer 30 and the second differentiator 32. The difference m is compared to the comparator, and the second differentiator 32 obtains a second difference D2 according to the sensing signal si and the second reference signal C2 并 and inputs the second difference D1 to the input comparator 34. The comparator 34 can estimate whether the power supplied to the bubble generator 22 is sufficient by comparing the magnitude of the first difference D1 and the second difference D2. For example, when the power supplied to the bubble generator 22 is sufficient, the bubble generator 22 can generate a larger or larger number of bubbles 202 such that the environment around the sensor 24 is closer to the flow path of the first reference component 26. Therefore, the result that the second difference ^2 is greater than the first difference D1 can be obtained. On the other hand, when the power supplied to the bubble generator 22 is insufficient, the bubble generator 22 generates a smaller or less bubble 202, causing the environment of the sensor 24 to be closer to the second reference element % of the flow path, and thus The first difference D1 is greater than the result of the second difference 02.
