Abstract: The present invention relates to virtual reality interaction technology, which is a virtual reality haptic feedback interaction system, comprising a head display module, a storage module, an electrical stimulation device, a time-division multiplexing circuit, and a flexible electrode array connected in sequence. The storage module receives haptic feedback parameters corresponding to virtual scene interaction events, and converts the corresponding haptic feedback parameters into corresponding electrical signals through its drive circuit; the electrical stimulation device controls the output pulse parameters of each electrical stimulation channel according to the received electrical signals. The time-division multiplexing circuit selects the optimal stimulation paradigm for each haptic experience, and outputs the corresponding pulse to the flexible electrode array. The present invention may enhance the experience effect in a virtual reality scene, and at the same time, by improving the structure and material of the electrode array, the electric stimulation methods are enriched, the accuracy of the electric stimulation is improved, and the immersion of the virtual scene is increased.

Abstract: A novel sweat absorbing textile electrode comprises a textile electrode body and an electrical coupling member, the textile electrode body comprising a conductive foam and a conductive fabric wrapped around the conductive foam, the electrical coupling member being fixed on the conductive fabric; wherein a through hole is provided on the conductive fabric on the side in contact with the human skin. The textile electrode has a light weight, small size and soft texture. It fits on the skin, has good air permeability, and is capable to absorb sweat, which can prevent short circuit between electrodes caused by sweat and be used for collecting bioelectrical signal when sweat comes out from human body. It may also be applied in bioelectrical signal monitoring in high temperature, high humidity environment, and during daily exercise.
