In residences of senior citizens, senior care homes, and hospitals, sudden changes in the condition of wheelchair users are sometimes overlooked, or they may fall from their wheelchairs. Thus, the taking of safety measures has become an increasingly difficult problem at various sites under the present circumstances. In this study, to overcome such problems, we developed a system to detect biological information without constraining the subject, which monitors the aged person or patient seated in the wheelchair. We devised an experimental method which pulses water through a tube intermittently to simulate blood flow in order to measure the characteristics of the sensor, and conducted a functional test of the system. The system has a structure in which the adapted Biological detector is pinched with piezoelectric sensors onto both sides of a stainless substrate 1 mm thick. We propose a piezoelectric method capable of detecting the heart rate and presence of the wheelchair user simultaneously.
