Development on Insole 3D Plantar Pressure Measurement System Based on Zigbee Technology
Plantar pressure measurement is now considered commonplace in the healthcare control and monitoring of normal people and patients, as well as having applications in military applications. Based on this need, we create a plan to construct a new insole plantar pressure system based on multifunction data acquisition modular, LabVIEW and Zigbee technology. Then the hardware and software parts are developed respectively. There are 3 sensors arrayed at each measurement point, that means 3 sensors are assembled in 3 different directions of X,Y and Z . The piezoelectric ceramic type sensors are designed, manufactured and calibrated according to scientific methods. Meanwhile, the DAQ card is selected carefully. Of course, the software part is developed based on LabVIEW. The singnal transmission and inception are performed based on wireless communication technology of Zigbee. A series of tests are performed in order to validate the function of the measurement system. The results satisfy the anticipated design requirements. The existing problems and application trend of the measurement system are predicted.
