Abstract
In general, a dielectric polymer substrate provided and an antenna formed upon the dielectric polymer substrate. A piezoelectric polymer layer (e.g., a polyvinylidene fluoride (PVDF) piezoelectric film) can be formed above the dielectric polymer substrate. Additionally, an interdigital (IDT) layer can be configured upon the PVDF piezoelectric layer, thereby permitting the piezoelectric polymer layer and the IDT layer to detect pressure data and transmit the data to a receiver via the antenna.
