研制了一种用于检测活体组织顺应性的新型触觉传感器探头。该传感器由一个Colpitts电路组成，包括一个1.5 mm/spl times/1.5 mm的压电谐振器，安装在直径为2.4 mm的底座上。这个尺寸足够小，可以插入人体。实验结果表明，振动频率随接触力的变化与物体的柔度有关。特别地，振荡频率-接触力曲线的最大梯度能够识别顺应性的差异。无需设置接触力常数即可测量精确的顺应性。
A new type of tactile sensor probe head which detects compliance of live tissue has been developed. The sensor consists of a Colpitts circuit including a 1.5 mm/spl times/1.5 mm piezoelectric resonator on a mount 2.4 mm in diameter. This size is small enough to be inserted into the human body. Experimental results show that the oscillating frequency change versus the contact force is related to the object compliance. Especially, the maximum gradient of the oscillating frequency versus contact force curve is able to identify the difference of the compliance. It is possible to measure accurate compliance without setting the contact force constant.
