In this project, we designed a circuit to capture the signal from the skin-like heart beat sensor and convert it to an electrical signal. The circuit is one part of the optical heart beat detection system which also includes the skin-like optical sensor array and the laser source and data processing unit. The circuit will be connected with the sensor array and be able to detect the sensing signal at each dot of the array. The sensor system could also be applied to contact form detection in other biomedical system.
