Abstract:
The roots of diagnostic techniques in Indian medical systems lie in the three radial pulses. Pulse reading is essentially a haptics technique in which the experts use various palpation techniques in order to mine the hidden physiological signals. In this paper we present the design principles we used and the design and analysis of a pressure pulse sensor using PVDF material for acquiring the three pulses from the radial artery. Sensitivity analysis of the design is also presented. The sensors are rmly held at each of the three radial points and by varying the pressure on the sensor head the recordings were done on 10 healthy subjects who had no history of cardiovascular disease. The shapes of the pulses were analyzed using frequency domain analysis and accordingly classi ed the subjects as vata, pitta, and kapha body type. Further we can also nd that the K90pulses are varying over time from morning, afternoon, to evening. Establishing that the three pulses provide information about the psychic characteristics is dif cult and it requires long term comprehensive, comparative research into both modern medicine and Indian medicine
