“…inertial driving, slant line driving and elliptical trajectory driving. The inertial driving method uses a proper combination of the frictional drive and abrupt contraction/extension of a vibrator [7,8], which is usually realized by a saw type driving voltage. But it is not easy to generate a pure saw type driving voltage, which lowers the energy efficiency of the motors.…”

“…In this mode of operation, the ratio between the times during which the friction force acts in either direction is the main factor determining the macroscopic velocity of the slider. To the author's knowledge, this basic relationship was first mentioned in literature by Morita et al [94] (p. 189). It was independently used as the basis of a specialised simulation technique for such motors by Hunstig et al ([87] (pp.…”

Piezoelectric inertia motors-also known as stick-slip motors or (smooth) impact drives-use the inertia of a body to drive it in small steps by means of an uninterrupted friction contact. In addition to the typical advantages of piezoelectric motors, they are especially suited for miniaturisation due to their simple structure and inherent fine-positioning capability. Originally developed for positioning in microscopy in the 1980s, they have nowadays also found application in mass-produced consumer goods. Recent research results are likely to enable more applications of piezoelectric inertia motors in the future. This contribution gives a critical overview of their historical development, functional principles, and related terminology. The most relevant aspects regarding their design-i.e., friction contact, solid state actuator, and electrical excitation-are discussed, including aspects of control and simulation. The article closes with an outlook on possible future developments and research perspectives.

“…Some studies have involved and presented significant improvements in producing non-sinusoidal periodical waveforms in the resonant state. 6,7 Study on this subject can also benefit some fields: if a mechanism can be used to produce a resonant arbitrary periodical vibration, it must be used to sense the signals at basic and harmonic frequencies with high sensitivities, and this has been used in tapping-mode atomic force microscopy, etc. 8,9 In this note, we propose a novel approach to match harmonics and vibration modes to realize arbitrary periodical vibrations in the resonant state.…”

We develop a novel approach to match harmonics and vibration modes based on the mechanism of multiple tuning fork structure (MTFS), through which it is promising to realize arbitrary periodical vibrations in the resonant state. A prototype three-layer MTFS with first three harmonics is presented to verify the feasibility of the proposed principle. The matching process and experimental results confirm the unique advantages of MTFS, as discussed in the theoretical analysis. Typical periodical motions, including sawtooth, square, half-wave rectified, and full-wave rectified waveforms, are achieved by the syntheses of resonant harmonics.
