Short summary
In this work, methods to reveal a symmetrical amplitude shape from the asymmetric behavior in thermally actuated piezoresistive cantilever sensors are proposed. The symmetrical amplitude shape should then be accompanied by a monotonic phase response. With the monotonic phase response, real-time frequency tracking can be easier to implement using a phase-locked-loop (PLL) system.
