Liquid Metal Based Flexible Electronic Patches for Wearable Device and CT Position Assistant

Electronic skin, which has a wide range of applications in biomedical devices, intelligent robots, and wearable devices, is provided with similar mechanical properties to human tissues. In this research, we developed a rapid preparation method of flexible electronic patches based on liquid metal. This technology uses a laser printer to realize the low-cost fabrication of flexible circuits in a short time. The flexible electronic patches are characterized by high electrical stability and good radiological imaging ability. We use this method to produce flexible patches with good electrical stability for the detection of body surface temperature. Besides, we also made a circular liquid metal flexible patch that could be applied on the surface of substances or the human body, which could realize the accurate localization of the lesions in the body with the help of CT.
