SAWGOOD (Wireless Stretchable SAW devices: a new path to multifunctional, on-skin, fully passive sensors)

The goal of the SAWGOOD project is to lay the groundwork to a new generation of imperceptible wireless on-skin stretchable surface acoustic wave sensors enabled by the combination of 3 aspects : efficient on-skin antennas, confined WLAW (Waveguiding Layer Acoustic Wave) structures in order to make packageless/self-protected structures, and advanced stretchable electronics micro-fabrication. The WLAW solution also makes it possible to push the miniaturization to its extreme by producing very low-profile components. The final goal is to make a “ready-to-tattoo” multifunctional sensors with a total thickness below 40 µm that will be passive, battery-less, wireless and packageless.
