With the rise of Internet of Things and Industry 4.0, piezoelectrics, or materials that generate electric charge when a strain is applied to them, are becoming extremely useful as compact and energy-efficient force sensors.
Accordingly, piezotronics has emerged as a new technological frontier with applications in structural health monitoring in civil engineering and human-machine interface devices.
Piezotronic force sensors are typically governed by either a strain-induced “Schottky barrier height (SBH) modulation” or by a “piezo-gating effect” that redistributes the charge carriers in an induced piezoelectric field.
