Rinaldi Awarded 2 Patents

July 19, 2017

ECE Associate Professor Matteo Rinaldi awarded 2 patents for “Nano- and micro-electromechanical resonators”.


Abstract Source: USPTO

A resonator including a piezoelectric plate and an interdigital electrode is provided. A ratio between a thickness of the plate and a pitch of the interdigital electrode may be from about 0.5 to about 1.5. A radiation detector including a resonator and an absorber layer capable of absorbing at least one of infrared and terahertz radiation is provided. A resonator including a piezoelectric plate and a two-dimensional electrically conductive material is provided.

A resonator includes a piezoelectric plate and interdigitated electrode(s). The interdigitated electrode includes a plurality of conductive strips disposed over a top surface of the piezoelectric plate. A two-dimensional mode of mechanical vibration is excited in a cross sectional plane of the piezoelectric plate in response to an alternating voltage applied through the interdigitated electrode. The two-dimensional mode of mechanical vibration is a cross-sectional Lame mode resonance (CLMR) or a degenerate cross-sectional Lame mode resonance (dCLMR).
