与假手一起使用的力传感器需要是小的、鲁棒的、低功率的、便宜的并且使用数字技术容易地与控制器接口。本文介绍的原型使用电容效应来测量弹性聚合物泡沫上的应变。低功耗导致可以由微型电池供电的设备，从而仅需要到控制器的信号线。非线性模型精确地描述了传感器的特性，仅需要估计三个参数。该设备已被测试高达20 N，但能够测量更大的力。
A force sensor, for use with an artificial hand, needs to be small, robust, low power, cheap and easily interfaced to a controller using digital techniques. The prototype featured in this paper uses capacitance effects to measure the strain on an elastic polymer foam. Low power consumption results in a device that can be supplied from a miniature battery thereby requiring only signal wires to the controller. A non-linear model accurately describes the characteristic of the sensor, requiring the estimation of only three parameters. The device has been tested up to 20 N but is capable of measuring greater forces.
