The fingerprint effect, wherein vibrations are produced with frequencies related to the speed of a surface sliding across fingerprint ridges and the period of those ridges, has been studied for use in both slip detection and texture recognition. Here, we use a simple bioinspired sensor with parallel, straight, fingerprint-like ridges and a single ferroelectric ceramic transducer to show that the f...
