Wireless, multimodal sensors for continuous measurement of pressure, temperature, and hydration of patients in wheelchair

Abstract Individuals who are unable to walk independently spend most of the day in a wheelchair. This population is at high risk for developing pressure injuries caused by sitting. However, early diagnosis and prevention these still remain challenging. Herein, we introduce battery-free, wireless, multimodal sensors movable system continuous measurement pressure, temperature, hydration skin interfaces. The device design includes crack-activated sensor with nanoscale encapsulations enhanced sensitivity, temperature measuring galvanic response levels. enables power harvesting, data communication multiple wireless devices mounted skin-cushion interfaces wheelchair users over full body coverage. Experimental evaluations numerical simulations devices, together clinical trials patients, demonstrate feasibility stability preventing
