Abstract
We propose and demonstrate a miniature microwave device capable of detecting wide-band ultrasound without the use of piezo materials. By the nature of the transduction mechanism, the scheme naturally implements orthogonal frequency division multiplexing (OFDM): each device can be assigned its own microwave band, mitigating electrical cross-talk between adjacent sensor elements for future imaging array systems. Furthermore, the entire array could be addressed with a single electrical connection, since addressing is in the frequency, rather than spatial, domain. We anticipate that the convenience afforded by this fully electronic platform will enable its use as a low cost and versatile solution in cases where high sensitivity is required over a large portion of the acoustic spectrum.
