Abstract—Smart gloves have attracted much attention as a typical representative of wearable human-machine interface (HMI). Traditional sensors on smart gloves are limited due to high cost, complex manufacture, which can’t meet the requirements of bio-friendliness and sustainability. This paper presents a smart glove human-machine interface based on strain sensor array of conductive hydrogels. A flexible, transparent, stretchable and sensitive hydrogel strain sensor is prepared based on a “one-pot” preparation method. The smart glove was constructed using 3D structural design combined with the sensor array. Combing with the signal processing system, the smart glove can realize the spatial motion control of the Unmanned Aerial Vehicle (UAV). The smart glove based on the hydrogel flexible sensor array showed great application prospects in the field of human-machine interaction of robot and Virtual Reality (VR).
