Claim 0:
1. A non-transitory computer-readable medium including instructions that, when executed by at least one processor included in a system, is configured to cause the system to perform operations comprising:
receiving a plurality of tactile waveforms representative of a pressure applied over a first time period;
decomposing each of the plurality of tactile waveforms into a lowpass component and a bandpass component via one or more filters, wherein the bandpass component corresponds to pressure fluctuations over the first time period due, at least in part, to blood flow, and wherein the lowpass component is representative of a baseline pressure corresponding to the pressure applied with at least some of the pressure fluctuations filtered out;
extracting features from at least one of the lowpass component and the bandpass component of each of the plurality of tactile waveforms; and
estimating blood pressure using a machine learning model to generate a fit of the features extracted from the at least one of the lowpass component or the bandpass component of each of the plurality of tactile waveforms.
