ZHOU Bin, GAO Zhong-yu, CHEN Huai, ZHANG Rong, CHEN Zhi-yong

Frontiers of Mechanical Engineering 2006, Volume 1, Issue 1,   Pages 106-110 doi: 10.1007/s11465-005-0016-5

Abstract:

A new digital readout system for micromachined gyroscope has been proposed to implement flexible parameteradjustment, improve the control performance of gyroscope, and make error compensation.By digitalizing the output of the gyroscope, this system uses a floating-type digital signal processor(DSP) to process the signal demodulation and achieve the feedback control of the gyroscope.Therefore, the small change of capacitance in the micromachined gyroscope can be detected.

Soft curvature sensors for measuring the rotational angles of mechanical fingers

Haixiao LIU, Li LI, Zhikang OUYANG, Wei SUN

Frontiers of Mechanical Engineering 2020, Volume 15, Issue 4,   Pages 610-621 doi: 10.1007/s11465-020-0596-0

Abstract: The design, fabrication, and testing of soft sensors that measure elastomer curvature and mechanical finger bending are described in this study. The base of the soft sensors is polydimethylsiloxane (PDMS), which is a translucent elastomer. The main body of the soft sensors consists of three layers of silicone rubber plate, and the sensing element is a microchannel filled with gallium-indium-tin (Ga-In-Sn) alloy, which is embedded in the elastomer. First, the working principle of soft sensors is investigated, and their structure is designed. Second, the relationship between curvature and resistance is determined. Third, several sensors with different specifications are built in accordance with the structural design. Experiments show that the sensors exhibit high accuracy when the curvature changes within a certain range. Lastly, the soft sensors are applied to the measurement of mechanical finger bending. Experiments show that soft curvature sensors can effectively reflect mechanical finger bending and can be used to measure the bending of mechanical fingers with high sensitivity within a certain working range.
