The continuous monitoring of hand gestures is a very challenging application due to the demanding requirements for robustness, accuracy, efficiency and cost effectiveness. Although several vision-based gesture sensors have made good progress in human action recognition, the human hand is a smaller object with more dexterity and is more easily affected by segmentation errors. In this paper, we present a novel chipless RFID-based hand gesture sensor utilizing stretchable silicone-based electrically conductive adhesives (silo-ECAs) which effectively create a “smart-skin”. The hand sensor uses wearable multi-resonator spectral signatures to encode data and to provide a unique ID for every hand gesture.
