Stretchable materials are frequently studied for the realization of strain sensors. The variation of the sheet impedance when an external mechanical stimulus is applied is employed to develop strain sensors. Several strain sensors have been proposed that use these materials but most of these require a hardwired system for sensor reading. Here a simple fully wireless strain sensor is proposed. The structure comprises a periodic surface whose elementary cell provides variable absorption as a function of the stretchable material sheet impedance.

Abstract
Stretchable materials are frequently studied for the realization of strain sensors. The variation of the sheet impedance when an external mechanical stimulus is applied is employed to develop strain sensors. Several strain sensors have been proposed that use these materials but most of these require a hardwired system for sensor reading. Here a simple fully wireless strain sensor is proposed. The structure comprises a periodic surface whose elementary cell provides variable absorption as a function of the stretchable material sheet impedance.File in questo prodotto:
