Quantitative detection of the status of the injured site of the patient contributes to the assessment of the rehabilitation effect. This paper designs a wearable device based on embedded system, which can get the pressure, temperature and attitude information of the finger parts and send these messages to terminal via Bluetooth communication technology successfully. Experiments show that the system can obtain the finger strength, flexibility, temperature and other information correctly, which can provide objective data for the evaluation of hand function rehabilitation.
