BLOOD PRESSURE ESTIMATION USING FINGER-WEARABLE SENSOR ARRAY

A finger-wearable blood pressure monitor device includes a cuff, a tactile sensor array, and control circuitry. The tactile sensor array is disposed on or adjacent to an inward facing surface of the cuff. The tactile sensor array includes a plurality of sensors. The control circuitry is coupled to the tactile sensor array and includes logic that when executed by the control circuitry causes the finger-wearable blood pressure monitoring device to perform operations. The operations include monitoring, over a first time period, a pressure applied to each of the plurality of sensors by a digital artery of a finger. The operations also include generating a plurality of tactile waveforms in response to monitoring the pressure. Each of the plurality of tactile waveforms corresponds to the pressure applied to a respective one of the plurality of sensors over the first time period. The operations further include estimating blood pressure based, at least in part, on the plurality of tactile waveforms.
