Electronic skin (E-skin) capable of detecting various physical stimuli is required for monitoring external environments accurately. Here, we report an all-soft multiaxial force sensor based on liquid metal microchannel array for electronic skin applications. The proposed sensor is composed of stretchable elastomer and Galinstan, a eutectic gallium-indium alloy, providing a high mechanical flexibility and electro-mechanical durability. Liquid metal microchannel arrays are fabricated in multilayer and positioned along a dome structure to detect multi-directional forces, supported by numerical simulation results. By adjusting the height of the dome, we could control the response of the multiaxial sensor with respect to the deflection. As a demonstration of multiaxial force sensing, we were able to monitor the direction of multidirectional forces using a finger by the response of liquid metal microchannel arrays. This research could be applied to various fields including soft robotics, wearable devices, and smart prosthetics for artificial intelligent skin applications.

基于液态金属的电子皮肤全软多轴力传感器

为了准确地监视外部环境,需要能够检测各种物理刺激的电子皮肤(E-skin)。在这里,我们报告了一种基于液态金属微通道阵列的全软多轴力传感器,用于电子皮肤应用。拟议的传感器由可拉伸的弹性体和Galinstan(一种共晶的镓-铟合金)组成,具有很高的机械柔韧性和机电耐久性。液态金属微通道阵列以多层形式制造,并沿穹顶结构放置,以检测多方向力,并得到数值模拟结果的支持。通过调整圆顶的高度,我们可以控制多轴传感器相对于偏转的响应。作为多轴力感测的演示,我们能够用手指通过液态金属微通道阵列的响应来监控多向力的方向。这项研究可应用于各个领域,包括软机器人,可穿戴设备以及用于人工智能皮肤应用的智能假肢。
