Wireless Electronic Tattoos

摘要: Wearable electronics are finding emerging applications in mobile health, rehabilitation, prosthetics/exoskeletons, athletic training, human-machine interaction, etc. However, our skin is soft, curvilinear and dynamic whereas wafer-based hard, planar, rigid. As a result, state-of-the-art wearables can only be strapped or clipped on human body. The development of flexible stretchable offers remedy for such challenge. E-tattoos represent class circuits, sensors, actuators that ultrathin, ultrasoft, skin-conformable deformable just like temporary tattoo. Our group has invented low-cost, dry freeform “cutsolder- paste” method the rapid prototyping multilayer reconfigurable wireless e-tattoos. This been proved to work thin film metals, polymers, ceramics, 2D materials their integration with rigid integrated circuits (ICs). Through modular design, we created e-tattoos wirelessly receive power transmit data through near field communication (NFC) Bluetooth. Such etattoos conform any part electrophysiological, mechanical, thermal optical sensing.
