Most of the papers on human body resistance are related to medical electrophysiology, such as polygraph research or electrical safety and electrical accidents. In this research, simple electronic circuits plus information processing are used. For hardware digital output control, everyone has different resistance values, and even the same person will have different human body resistance values at different time periods and physiological states. There is no regular change to follow, and there is no stability. The status is originally difficult to determine the authenticity. With the popularity of the Internet and the coverage of wireless connections, it will be used as real-time sampling and database values for authenticity comparison, so the smart switch application of human resistance will be used as a new way for applications such as access control.
Because of the popularity of wireless networks, IoT related applications are in the ascendant. The combination of the smart switch application of human resistance and the concept of IoT will be a new type of thinking. After all, wearable devices are already needed in daily life. The IoP (Internet of People) will also be a form of technological life that is being perfected, and the application of smart switches for human resistance will be the important features of IoP.
In the field of character recognition, the previous emphasis was on sampling fixed and unique biological characteristics, such as fingerprints, tooth patterns, voiceprints, retina, and even DNA testing. This is based on fixed biological characteristics as the basis for judging authenticity. Resistance is in an unstable state and exists in daily life. How to sample the biological characteristics of the unstable resistance of the human body is the main purpose of this research.
