Design of a trigeminal neuralgia pressure-pained-detector based on MSP430

A pressure-pained-detector for trigeminal neuralgia based on MSP430 ultra low-power MCU is described. According to the characteristic of human trigeminal neuralgia, an excellent pressure-pained-detector is designed. A high precision medical pressure sensor is used to get pressure-pain signal, and it can convert the pressure signal to a tiny voltage signal. The multi-sensor information fusion technology is applied to improve precision of data collection. The tiny voltage signal can be amplified within the 0-2.5 voltage by the multi-stage amplify circuits, then the signal is processed by MSP430. The voltage signal not only can be dynamically shown by LCD but also can be transmitted to PC for further analysis and managing. By experiment it is shown that the detector has some excellencies such as high precision, anti-jamming, simple structure of circuit, convenience of operation, high practicality.
