The Stability

Pressure sensors are commonly used in industrial production and mechanical system. However, resistance strain, piezoresistive sensor, and ceramic capacitive pressure sensors possess limitations, especially in micro force measurement. A surface acoustic wave (SAW) based micro force sensor is designed in this paper, which is based on the theories of wavelet transform, SAW detection, and pierce oscillator circuits. Using lithium niobate as the basal material, a mathematical model is established to analyze the frequency, and a peripheral circuit is designed to measure the micro force. The SAW based micro force sensor is tested to show the reasonable design of detection circuit and the stability of frequency and amplitude.

Accuracy And Repeatability

This paper presents the development of a sixaxis force/torque (FTS) sensor using crossbeams for a robotic arm. The sensor produced in this paper is a new unique design that was developed under rigorous trial and testing using finite element analysis (FEA) at every stage of development. Additionally, the FTS presented uses strain gauge technology and data-acquisition (DAQ) to measure and record forces in Fx, Fy, and Fz direction along with torque in Mx, My, and Mz direction. FTS was tested, calibrated, and fitted on a robotic arm to test its accuracy and repeatability

Strain Type

A piezoelectric gripper with force sensor is presented for an optical precision manipulation. The gripper utilizes flexure hinge mechanisms with two-step amplification to achieve output displacement. Micro displacement amplification principle of the gripper is analyzed and verified using finite element analysis (FEA) soft. A force sensor of resistance strain type with elastic plate structure of bi-cantilever is designed, which is fixed at the bottom of the gripper to detect force signals during the working process. The strain foils adopt a connecting method of full-bridge. According to theoretical analysis and FEA of the force sensor, bonding positions of the strain foils are determined. Experimental results indicate that the sensor has good linearity and little temperature drift and creep, and its resolution is less than 100mN. Micro-vision method is used to test the gripper, and maximum displacement is 302μm.
