Design of ‘Floating, Medium and Sinking’ Pressure Simulation System for Remote Reduction of Pulse Condition in TCM

In order to solve the problem of simulating ‘floating, medium and sinking’ in remote diagnosis of TCM (Traditional Chinese Medicine), we designed a set of ‘floating, medium and sinking’ pressure simulation system which can feedback the remote pulse condition, including automatic pressurization device and pressure detection feedback device. The system uses a piezoresistive sensor to collect the compression force at the bionic prosthetic hand of the pulse recovery terminal and sends it back to the pulse collection terminal. The automatic pressure device at the collection end simulates the TCM doctor to automatically find the appropriate pressure intensity. In this paper, the pulse collection algorithm and pulse reduction algorithm are designed to make the pulse recovery more accurate. Through the collection of a large number of experimental data, and the experience of some professional doctors of TCM, it is believed that the system can well simulate the actual pulse process of ‘floating, medium and sinking’ pressure.
