Prototype of a simple insole type sensor measuring the reaction force received by the legs for the purpose of measuring the burden on the body

Abstract

In recent years, the necessity of measuring the physical stress is increasing. The reaction force that the legs receive from the floor is useful information for estimating the physical stress. But measurement equipment for reaction force cannot be carried in most cases. It is difficult to measure at the environment that human act. Furthermore, that equipment is expensive, and measurement involves several constraints. We prototype a sensor which is low cost and can measure the reaction force even in any environment.
