We present modeling, design, fabrication and characterization of a new type of all-optical frequency modulated MEMS force sensor based on a mechanically amplified double clamped waveguide beam structure with integrated Bragg grating. The sensor is ideally suited for force measurements in harsh environments and for remote and distributed sensing and has a measured sensitivity of -14 nm/N, which ...
Carpal tunnel syndrome (CTS) refers to a class of injuries characterized by compression of the median nerve in the carpal tunnel. CTS injuries cause pain, weakness, and numbness in the hands and are common among video gamers and workers that maintain their wrists in ergonomically unfavorable positions. Current CTS qualification methods are well documented, whereas the condition of the hand musc...
A force sensor based method to detect the instant of needle puncture to the layers of tissues is proposed. A set of needle and sheath attached to a pair of coaxial force sensors was used to separately measure the cutting force at the needle tip and the sidewall friction. Change of the force profile was observed and marked at the instant of the puncture, and robustly eliminated artifacts caused ...
This paper presents a multi-axis force/torque sensor based on simply-supported beam and optoelectronic technology. The sensor's main advantages are: (1) Low power consumption; (2) low-level noise in comparison with conventional methods of force sensing (e.g., using strain gauges); (3) the ability to be embedded into different mechanical structures; (4) miniaturisation; (5) simple manufacture an...
