Claim 0:
1. A method comprising:
generating a displacement signal indicative of a distension of a surface of a skin;
determining temperature values indicative of measured temperatures of the skin using a temperature sensor;
during a calibration time interval,
collecting a plurality of distension values from the displacement signal, the plurality of distension values associated with a respective plurality of the temperature values determined using the temperature sensor, wherein the plurality of the temperature values are indicative of a temperature change of the skin, and
applying energy to the skin or removing energy from the skin to cause the temperature change of the skin;

determining compensation coefficients associated with the plurality of the temperature values; and
after the calibration time interval,
collecting a first distension value from the displacement signal, the first distension value associated with a respective first temperature value of the temperature values, wherein the first distension value is separate from the plurality of distension values, and the first temperature value is separate from the plurality of the temperature values, and
determining a blood pressure based on the first distension value, the first temperature value, and the determined compensation coefficients.
