Probing electromechanical coupling in biological systems and electroactive molecules requires high resolution functional 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 imaging at frequencies corresponding to the first contact resonance in liquid allows contrast consistent with the electromechanical signal to be obtained for model ferroelectric systems and piezoelectric tooth dentin
