Special Issue Information

Dear Colleagues,

Piezoelectric and piezoresistive materials have been well-tailored for mechanical and bio sensors, thanks to their excellent properties, such as high sensitivity, simple readout circuit, and miniaturization capability. Applications of these effects can be found in a broad range of Micro/Nano ElectroMechanial System (MEMS/NEMS) sensors, including strain sensors, pressure sensors, accelerometers, and bio-mass detectors. This Special Issue focuses on cutting-edge technologies of piezoelectric and piezoresistive materials, aiming at advanced developments of nanostructured, flexible, wearable, and self powered sensing-devices. We greatly welcome review papers, experimental studies, as well as theoretical analyses, of novel piezoelectric and piezoresistive materials.

In particular, topics of interest include, but not limited to:

  • Advanced deposition/growth processes of piezoelectric and piezoresistive thin films;
  • Characterization of novel piezoelectric and piezoresistive materials;
  • Quantum confinement and nanoscale effects in piezoresistive/piezoelectric materials;
  • Advanced micro/nano fabrication methods;
  • Applications of the piezoelectric and piezoresistive effects.

Modeling and waveform optimization are important research topics for piezo-actuated stick–slip micro-drives. In this paper, the dynamics of piezo-actuated stick–slip micro-drives (PASSMDs) are theoretically investigated. We introduce an extended model taking the dynamics of the piezo actuators into account. The model combines the whole macroscopic movement of the drive’s runner and actuators and the microscopic behavior of the frictional contacts in a hybrid dynamic simulation. The macroscopic movements are described via Newtonian mechanics, while the microscopic behavior is computed using the method of dimensionality reduction. Two important characteristics of the drive, the critical actuation amplitude and the force generation, are systematically analyzed. The numerical simulation results show a fine agreement with experimental data of the previously published work. The critical actuation amplitude is found to depend on the behavior of the guiding contacts, the dynamics of the actuators and their interaction. Furthermore, a novel driving waveform, which allows us to increase the operational velocity for the drive, is proposed. The waveform is derived by exploiting micro-vibration and considering the dynamic contact status. Simulation results show that the average velocity of the drive is heightened by about 15 % . The performance of the drive is therefore improved. Full article
