Patent number: 9848775Abstract: Aspects of the present disclosure are directed to pressure sensing. As may be implemented in accordance with one or more embodiments, an external energy field is applied to a resonant circuit having inductive conductors separated by a compressible dielectric, for wirelessly detecting pressure.
