Abstract : This article presents a conformal and on-body RF sensor with reduced wiring complexity for tremor detection in Parkinson's disease evaluation. RF sensor aids in detecting and extracting continuous finger movement that makes exact and repeated estimation of tremor feasible. The shift in frequency during finger motion is investigated to monitor tremor. The sensor is developed on a finger cap in such a way that it conforms to the shape of a human finger. The realized sensor can detect relative angle changes with an accuracy of 0.57 o . The fabricated sensor is tested in real-time with variations in finger length, diameter, and skin thickness. The influence of these variations on the frequency shift is investigated using analysis of the variance and fuzzy method. The correlation value of 98% between experimental and predicted values is obtained using the fuzzy logic.
