DONG Wan-cheng, HUANG Ying, MING Xiao-hui, et al. Design of signal processing circuit for new flexible tactile array sensor[J]. 2009, 28(9): 75-78. DOI: 10.13873/j.1000-97872009.09.022.
Based on the use of piezoresistive effect of a 3×3 matrix of flexible tactile sensor
a new signal processing circuit is designed.The circuit can fulfill requirement as follows:signal amplification
choosing signal from sensor array
A/D conversion and collecting signal by LED circuit.And the principle and the circuit chip with the function are detailed.The signal processing circuit designed can determine which suffered three-dimensional tactile sensor unit load size and position of power.Through the loading experiment at positive pressure
