Hand Rehabilitation System Based on Flexible Pressure Sensor

Abstract

With the development of the social economy, the demand for rehabilitation medical devices is also increasing. However, most rehabilitation devices on the market currently have problems such as bulky equipment, inconvenient operation, and high cost. Taking hand grasp force as the main monitoring parameter, this paper designs a low-cost hand rehabilitation system that is convenient to use, can remotely monitor the progress of hand rehabilitation. The system can well solve the large volume of equipment caused by the complex structure of the existing hand rehabilitation equipment. It can also solve the problems that the device cannot obtain the data of the patient’s recovery in real-time and the use cost is too high. The system includes five modules: flexible pressure sensor module, voltage conversion module, microcomputer module, LCD module and NB-IoT communication module. The flexible pressure sensor module can be attached to the patient’s hand to monitor the recovery data in real-time and see the recovery progress visually on the LCD screen. In addition, rehabilitation data can be uploaded remotely through the NB-IoT communication module for remote guidance by professional doctors to speed up the process of hand rehabilitation.
