适老化无感可穿戴低功耗防走失心率检测鞋的设计与实现OA

Aiming at the real pain points of health monitoring and safety protection for elderly people living alone in the community,we have developed an age-friendly and non-sensing wearable shoe that combines heart rate monitoring and anti-loss functions to solve the problems of high power consumption and inconvenient wearing of traditional wearable devices.Using PPG photoelectric sensing technology,multi-mode positioning fusion technology and low-power hardware optimization scheme,combined with ergonomic design,product development was completed;the heart rate monitoring accuracy,positioning error and endurance of the device were verified through laboratory testing,and 50 people lived alone in the community A one-month trial survey was conducted for elderly people living alone.The product's heart rate monitoring accuracy reaches±2 beats/minute,outdoor positioning error is≤3 meters,indoor positioning error is≤5 meters,and the average battery life on a single charge is 8.2 days;the trial satisfaction of elderly users reaches 89%,of which the wearing comfort score is 92%.The testing shoe achieves the functional integration of"health monitoring+safety protection".The aging-friendly design adapts to the usage habits of the elderly.It can provide technical support for community elderly care services and has high practical value.
