“…Changes in contour shape as well as intensity of the pressure pulse waveform are caused due to decreasing arterial/capillary diameters, decreasing pressure and are also contributed by the total distensibility of the arterial tree [14]. On lines similar to authors previous works [10,11,12], a capacitance based pulse sensing mechanism has been used for signal sensing ( Figure 1). An electret capacitive pick-up (typical CMA-4544PF-W available from DigiKey part no 102-1721-ND), and having a near flat frequency response up-to 20 kHz is used for sensing the radial pulse perturbations.…”

“…Conventionally TIM physicians solely rely on sense perception for Va, Pt and Kp identification and quantification. The present study, similar to earlier [10,11,12], attempts to identify signal processing based measures/ parameters for identifying Vt, Pt and Kp humors for achieving an objective outlook. This can help in the realisation of a low cost, non-invasive diagnostic tool as a value added aid for physicians.…”

Objective analysis and interpretation of radial pulse signal has been attempted. Capacitance variation based sensing and instrumentation mechanism has been developed for pulse sensing and logging. Traditional Indian Medicine (TIM) perspective for humor identification has been attempted. Pulse signal of healthy individual analysed in dominant humor interval, display prominent changes in recurrence quantification measures for pulse amplitude variations. These marker results are observed to correlate strongly with those obtained for a group of healthy individuals in a dominant humor interval period. Recurrence quantification analysis can possibly help in arriving at inferences apparent to sense perception for a TIM physician.
