Abstract

In this paper, we designed a portable digital pressure algometer which not only can measure the pain level objectively and quantitatively, but also is able to do RF communication. This system consists of pressure sensor for pain measurement, analog signal analysis, digital hardware based on PIC16C73B, RF communication and display. To evaluate the performance of the developed system, we measured pressure threshold using commercial analog PA(Pressure Algometer) and the proposed system, and then evaluated the correlation and confidence. Using linear regression analysis, standard deviation of 0.1731 and R-square value of 99.3% were obtained. In conclusion, the above results showed good performance and its usability in measuring the pain clinically.
