This paper reports a microelectromechanical systems (MEMS) mirror with electrothermal polymer actuators for the diffusion sensor. A compact and high-speed diffusion sensor is desirable for point-of-care testing because of its real-time monitorability and portability. and because diffusion coefficient reflects the abnormality of biological samples such as proteins.
