本报告展示了一种基于弹性体的可穿戴电子皮肤，包括用于监测手指关节的电阻式传感器和用于记录沿着手指整个长度分布的压力的电容式触觉压力传感器。通过将柔软的可压缩硅酮泡沫用作介电和可拉伸的薄金属膜，实现了对于5至405 kPa的压力（包括大部分人类生理感测范围）的0.001至0.01 kPa（-1）量级的压力灵敏度。将这些传感器集成在纺织手套中，可以解耦触觉传感器的应变和压力交叉敏感性，从而实现精确的抓握分析。传感器手套在人在环系统中实现，用于控制物体的抓握，这是实现具有集成传感能力的手部假体的关键一步。
This report demonstrates a wearable elastomer-based electronic skin including resistive sensors for monitoring finger articulation and capacitive tactile pressure sensors that register distributed pressure along the entire length of the finger. Pressure sensitivity in the order of 0.001 to 0.01 kPa(-1) for pressures from 5 to 405 kPa, which includes much of the range of human physiological sensing, is achieved by implementing soft, compressible silicone foam as the dielectric and stretchable thin-metal films. Integrating these sensors in a textile glove allows the decoupling of the strain and pressure cross-sensitivity of the tactile sensors, enabling precise grasp analysis. The sensorized glove is implemented in a human-in-the-loop system for controlling the grasp of objects, a critical step toward hand prosthesis with integrated sensing capabilities.
