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.
