适用于阿尔茨海默患者的智能穿戴式设备

为了减轻阿尔茨海默病患者的病痛和缓解看护人员的负担，研制一套基于信号采集和无线通信的智能可穿戴设备。该设备通过将PVDF( Polyvinylidene Fluoride) 传感器紧贴患者足底，经采集、电荷/电压转换、调理电路获得患者足部压力变化，并判断其行为，同时可以通过GPS( Global Positioning System) 获取患者位置信息，以短信形式实时通知看护人员，并具备紧急通知功能。实际应用表明，这套适应于阿尔茨海默病人的智能可穿戴设备可以有效帮助看护人员照顾患者，保障患者安全。

Intelligent Wearable Devices for Patients with Alzheimer's Disease

Alzheimer's disease is a common disease and is harmful to the elderly． At present，there is no effective cure for Alzheimer's disease． It can only reduce the harm of Alzheimer's disease to the patient，family and society through nursing． Alzheimer's disease is a chronic disease and the nursing cycle is long，so it often causes great physical and mental stress to the nursing staff． In order to reduce the patient's pain and relieve the burden of the caregivers，an intelligent wearable device based on signal acquisition and wireless communication is developed． On the one hand，it can monitor the patient's behavior in real time． The patient's foot pressure changes are collected by PVDF ( Polyvinylidene Fluoride) sensors，then the behavior is notified and the caregiver is notified to ensure patient safety． On the other hand，we can locate the patient's position information by GPS( Global Positioning System) and notify the caretakers in real time by SMS ( Short Message Service) ，and the device has the function of emergency notification． This smart wearable device adapting to Alzheimer＇s patients can help the caregivers take care of the patients and ensure the safety of the elderly．
