A Wearable Glove with Electrothermal‐Controlled Ionogels for Adhesive Gripping

Abstract

In this article, a lightweight, untethered wearable adhesive glove (total weight 72 g) is developed to empower the human hand with adhesive gripping. A textile glove comprises ionogels with embedded flexible heaters and a wireless electronic control module. The thermoresponsive ionogel with switchable adhesion achieves a switching ratio of 4.9 after heating 4.4 s under 4 V voltage, enabling on‐demand object pickup and release. As demonstration examples, the wearable adhesive glove is shown to grasp multiple objects with single‐finger adhesion and manipulate card with two‐finger adhesion. It is shown in the experiments that the wearable adhesive glove can expand the gripping modes and enhance the gripping ability of the human hand by giving it a new degree of freedom of adhesion.
