Abstract :
The stability of response with time is assessed for an elastic RFID tag acting as a strain gauge sensor. The design uses conducting Lycra to provide the metallic layer and the substrate is formulated from elastic PDMS material loaded with barium titanate to increase the relative permittivity. The tag is capable of 20% longitudinal strain and offers an almost linear response with negligible drift over time.
