Abstract: A femtosecond (fs) laser-written cladding waveguide phase-shift FBG(CWPS-FBG) structure was demonstrated for high-precision blood pressure (BP) measurement. This structure primarily consists ...
Abstract: This article presents a quadrature phase-locked-loop (QPLL)-based digital system for closed-loop control of micro-electromechanical system (MEMS) resonant sensors. The system estimates the ...
