title: Motion artifact reduction in blood pressure signals using adaptive digital filter with a capacitive sensor.
abstract: Motion artifacts can degrade the quality of data measured. In this paper, we suggest a capacitive sensor application which is able to be fabricated easily and employed for adaptive filtering. When the motion artifacts occur, the capacitance varies as well. Thereby, the capacitance data coincide with the motion artifacts. The capacitance data synchronous with the motion artifacts and the corrupted blood pressure signal were applied to the adaptive digital filter so that motion artifacts in blood pressure signal managed to be removed successfully.
