Wearable technology for measuring biomedical signal and momentum has been advanced for the purpose of physiological monitoring system during daily life. In measuring ground reaction force, a method to estimate plantar pressure from output of compact force sensors on the underside of footwear has been used. However, compact sensors used in this method are expensive, it is hard to use these sensors in daily monitoring of sports activity and rehabilitation. In this paper, the authors adopted low-priced film force sensors instead of the compact force sensors, and measured load on plantar and made it possible to estimate vertical ground reaction force in walking. In addition, the authors confirmed that this monitoring system can be used in different pace and footwear.
