Probing electromechanical coupling in biological systems and electroactive molecules requires high-resolution imaging. Here, we investigate the feasibility of intermittent contact mode piezoresponse force microscopy based on simultaneous mechanical and electrical probe modulation. It is shown that the combination of (a) imaging at frequencies corresponding to the first contact resonance in (b) liquid allows contrast consistent with electromechanical signal to be obtained on model ferroelectric perovskites and tooth dentin.
