Measurement of static electricity generated by human walking

Electrical charge phenomena often cause problems in our daily lives. For example, static electricity that builds up in the human body can cause pain when it discharges. Since static electricity is not visible to, it is difficult to detect and prevent its discharge. In this paper, we describe a newly developed static electricity sensor and its performance in our experiments. The static electricity charged when walking is synchronized with the walking steps. The static electricity was openly detected by a bioelectric amplifier. We attempted to use the change in output voltage in synchronization with walking as a walking step counter as well as walking form checker. Here, as a basic study, we investigate the relationship between the feet and the floor.
