Abstract: This paper presents a capacitive displacement sensor interface circuit based on T-network notch feedback and phase sensitive detection, and verifies the feasibility and advantages of the ...

Abstract: This paper presents a CMOS automatic gain control (AGC) readout circuit for Micro Electro-Mechanical System (MEMS) resonant pressure sensor. The oscillation conditions for MEMS loop and the ...

Researchers developed a single-use sensor strip that can be used with a circuit board to detect cerebrospinal fluid leaks. They collected nine clinical samples and introduced the test fluid into a ...
