Abstract
A pressure sensing device that includes a pressure sensing element that is of microscopic scale and has a pressure level dependent thermal parameter; a signal source that is configured to supply an input electrical signal to the pressure sensing element; and a monitor that is configured to (a) measure electrical output signals generated by the pressure sensing element as a result of the supply of the input electrical signal and (b) estimate a pressure level applied on the pressure sensing element based on the electrical output signals.
