摘要: This paper presents a novel sensing microgripper based on silicon-polymer electrothermal actuators and piezoresistive force cantilever beams which can monitor the displacement of jaws also contact between tips gripped object. A jaw motion up to 32 mum with an output voltage 49 mV 114 mW power consumption is measured at driving 4.5 V. The working temperature structure then 177degC. sensitivity 1.7 V/N corresponding 1.5 kV/m. minimum detectable 1 nm 770 nN are estimated, respectively.
