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.

“…The frequency, slewrate, and amplitude of the control signal can be regulated. The preload, responsible for the normal force in the contact zone between the ruby hemispheres and the runner's surfaces, is created by the weight of the runner itself and has also a direct impact on the achievable force [4].…”

Assessing material properties on the micro and nanoscale requires appropriate tools and measurement systems. Micro- and nanorobotic systems allow for such investigations. This contribution represents a case study in this respect. A setup capable of compressing single fibres with force feedback under scanning electron microscopy observation is presented and used. Variations in the compression force during testing of single fibres are reported and analysed. It is shown that significant alterations of the fibre wall mechanical properties are already introduced during testing one fibre several times in the transverse direction. Although hornification is generally used in the context of changes on the fibre wall due to drying and rewetting cycles of fibres or paper, it is suggested to expand the term also on changes induced by mechanical treatment, as the outcome could be similar. Furthermore, a microrobotic method and a system are proposed which will allow simulating the mechanical hornification and which are based on a force generating apparatus.

“…In practice this is not true, as will be shown later on. Edeler et al (2010) presented the influence of preload on the zero-step amplitude. The zero-step amplitude is the minimum control signal's amplitude which is needed to generate stick-slip steps.…”

“…Amplitude and frequency together determine the runner's velocity and slewrate is supposed to be high enough to enable a reliable change from stick to slip. Investigations on the influence of the slewrate can be found in Edeler, Meyer, & Fatikow, 2010. In the following section it is shown that the control amplitude can be used to modulate the generated force.…”

In this paper a new method to generate forces with stick-slip micro drives is described. The forces are generated if the runner of the stick-slip drive operates against an obstacle. It is shown that the generated force can be varied selectively without additional sensors and that virtually any force between zero and a limiting force given by certain parameters can be generated. For the investigated micro actuator this force is typically in the range up to hundreds of mN. For this reason, the method has the potential to expand the application fields of stick-slip positioners. After the presentation of the testbed containing the measured linear axis, measurements showing the principle and important parameters are discussed. Furthermore, it is shown that the force generation can be qualitatively simulated using state-of-the-art friction models. Finally, the results are discussed and an outlook is given.
