Abstract:
In accordance with the bulky volume and not easy to carry of pain detection equipment limitations, designs a kind of portable high-precision dolorimeter based on STM32. Using the high precision pressure sensor pressure contact as the main body to make the pressure pain signals. Through the signal preprocess of the amplifying circuit and the filter circuit, to eliminate the system noise effectively. Use the TFT-LCD to display the real-time measured pressure value, and establish a pressure pain threshold of the object. The USB interface transmits the data to PC to store, and it's beneficial to the diagnosis and treatment of subsequent.
