Definitions

  • the proposed apparatus relates to epidermal electronics - electronic devices that are thin and attached (affixed) to the user's skin with an adhesive.
  • a big problem with current epidermal electronics is that electrodes are often glued to the skin and are painful to remove. Current removal approaches are mechanical or chemical. Current removal generally degrades or destroys the electronics.
  • the proposed apparatus relates to epidermal electronics - electronic devices that are thin and attached (affixed) to the user's skin with an adhesive. These devices can be used for many purposes (such as sensing user physiology).
  • epidermal electronics are being considered for use as input devices for augmented reality (AR)/virtual reality (VR) applications. For example, measuring the electrical impedance of the hand/wrist/arm to allow for gesture input to AR/VR.
  • AR augmented reality
  • VR virtual reality

  • sensors include one or more of temperature sensors, ECG and EMG sensors.
  • the at least one heating element is one of non-resistive and resistive.
  • the layer having heating elements and the circuit layer are implemented on a same layer.

It is thus regarded that any means that can provide those functionalities are equivalent to those shown herein.
  • the proposed apparatus uses a heat sensitive glue.
  • a glue that loses adhesion when it is heated above a given temperature (for example, 110 degrees Fahrenheit which is warmer than the body and the environment but not perceived by the user as "hot”).
  • a variety of heat sensitive adhesives can be used. Each of the glues loses its adhesive property in a slightly different range so the temperature at which the adhesive property of the epidermal electronics is automatically released depends on the particular adhesive that is used.
  • the epidermal electronics device is adhered to the user's skin with a heat sensitive adhesive.
  • the proposed apparatus also uses a heating element in the epidermal device.
  • the heating element is one of a resistive coil or a non-resistive heating element.
  • the layer having the heating element may be a separate layer in the epidermal electronics, or the layer having heating element could fill in areas not occupied by the epidermal electronics circuit. It could also use the ground plane as the conductor applying a short circuit across that region. This heating element could be for the entire surface area, or only certain regions could have the glue and the restive circuit placed only in those corresponding areas. Other heating mechanisms could also be used such as Peltier devices, etc.

  • Fig. 2 is an exemplary embodiment of the proposed apparatus in accordance with the principles described herein.
  • the proposed apparatus has multiple layers.
  • the proposed epidermal electronics are attached to a user's skin 220.
  • the proposed epidermal electronics includes a first layer of heat sensitive adhesive (glue) 205.
  • a layer having heating elements (resistive or non-resistive) 210 is affixed to the layer of heat sensitive glue (adhesive).
  • the layer having heating elements is shown as encompassing the entire layer, however, the layer having heating elements may encompass only a portion of the layer. For example, the layer having heating elements may be on the periphery of the layer thus, allowing additional circuitry to be included in this layer.
  • the layer having heating elements is heated to a temperature sufficient to cause the heat sensitive layer to automatically release the entire epidermal electronic device from the user's skin.
  • Different heat sensitive glues have slightly different temperature ranges that will cause the automatic release of the epidermal electronics to release.
  • a goal is to select a heat sensitive glue (adhesive) that is above a user's normal temperature but not hot, where hot would cause the user pain or a burn but that is sufficiently hot to cause the automatic release of the epidermal electronics.
  • An additional layer of circuitry 215 is also envisioned.
  • the epidermal electronic circuitry may include a processor or CPU, sensors, radios, antennas, RF coils, RF diodes etc.
  • Sensors may include, for example, ECG, EMG sensors, temperature sensors etc. It is also possible to include an additional layer of a temporary tattoo, which is especially useful for biometric epidermal circuitry used with children.

  • the proposed epidermal electronics apparatus is affixed to skin of a user.
  • the proposed epidermal electronics apparatus is used for its intended purpose, for example, biometric screening or biometric measurements or AR/VR control.
  • sufficient heat is applied to the proposed epidermal electronics apparatus to cause it to be automatically released from the skin of the user.
  • Fig. 4 is a chart of skin (surface) temperatures of a person at various points on the person's body. Surface body temperatures (skin temperatures) or what the user's skin may come into contact are important considerations. As can be seen from Fig. 4, the placement of the epidermal electronics apparatus (device) and its use determine a reasonable operating range. If the epidermal electronics apparatus (device) is placed in the underarm area or underclothes or is to be used while exercising then a higher temperature will be needed to cause the epidermal electronics apparatus (device) to automatically be released from the skin of the user. In most instances the epidermal electronics apparatus (device) will probably be placed on the torso, or hands/arms. A reasonable operating range for the selected heat sensitive glue (adhesive) could thus be as low as 86 °F (30 °C) to 122 °F (50 °C).
