Patient transfer during nursing care imposes a heavy burden on long-term caregivers, frequently causing back pain. It is therefore necessary to improve nursing skills in order to reduce the burden on caregivers so as to prevent accidents. In this study, we fabricated capacitive body-pressure and proximity sensors that use conductive texture for detection, in order to evaluate nursing care movements. To investigate the response of the sensor, an experiment was conducted in which a stainless block was brought close to and then placed in contact with a simulated living body. The results show that the sensor can detect the distance to a living body, in addition to the applied pressure. Based on these response characteristics, a sitting experiment was conducted in which 10-channel body-pressure and proximity sensors were installed. The results indicated that the proposed sensor can be used to analyze the seating position of patients in a wheelchair based on the pressure on the seat surface.

In this study, we developed a capacitive seating analysis sensor using a conductive textile for evaluating a Seating Motion. Physical burden on caregivers is a common problem at nursing care sites. Developing long-term caregiving skills can help reduce the physical burden on amateur caregivers. Several quantitative evaluation studies have focused on the skills of caregivers. However, such evaluation is highly expensive and require huge area because it involves the use of motion capture systems with several 3D cameras for dynamic motion analysis. In our previous study, we developed a conductive textile sensor for measuring the seating position of a care recipient in a wheelchair. The sensor could measure either seating body pressure or distance between the buttocks and the seat. The system can measure the care recipient's motion without requiring any motion capture system. We recommend using the sensor to evaluate the skills of caregivers; the sensor output can be used to determine the seating speed of the care recipient on the chair. Herein, we report the validity of the measurement system comprising a conductive textile-based capacitive seating analysis sensor for evaluating seating in nursing care.
