TL;DR: In this paper, an ultra-fast electrothermal bimorph micromirror with an inverse-series-connected actuator, which is made up of Cu-W bimomorph, was reported.
Abstract: This paper reports an ultra-fast electrothermal bimorph micromirror with an inverse-series-connected bimorph actuator, which is made up of Cu-W bimorph. This mirror has a high rotational resonant frequency of 12.8 kHz.

TL;DR: A tunable inductor using a process fully compatible with CMOS has been constructed, and the tuning range achieved was 30%.
Abstract: Inductors play an important role in wireless front-end circuitry. Tunable inductors can provide more flexibility in optimizing RF devices such as filters and VCOs. A tunable inductor using a process fully compatible with CMOS has been constructed. The tuning range achieved was 30%.

TL;DR: In this article, a solid state image-sensing device is described which includes a base board fitted with a plurality of connection pins, an interline transfer charge coupled device serving as an area sensor, and a pair of bimorph piezoelectric vibrating elements which jointly vibrate to periodically vibrate the IT-CCD relative to an incoming image light in a plane substantially parallel with the surface of the base board.
Abstract: A solid state image-sensing device is disclosed which includes a base board fitted with a plurality of connection pins, an interline transfer charge coupled device (IT-CCD) serving as an area sensor, and a pair of bimorph piezoelectric vibrating elements which jointly vibrate to periodically vibrate the IT-CCD relative to an incoming image light in a plane substantially parallel with the surface of the base board, and wherein the piezoelectric vibrating elements are elastically held above the base board by support plates having a spring action, thereby efficiently vibrating the IT-CCD.

TL;DR: In this article, an STM was built, in which the substrate is mounted on a piezoelectric bimorph, and the compliance of the tip-surface contact region is measured by modulating the vertical position of a tip and detecting the induced deflection of the bimomorph.
Abstract: SUMMARY
An STM was built, in which the substrate is mounted on a piezoelectric bimorph. The compliance of the tip-surface contact region is measured by modulating the vertical position of the tip and detecting the induced deflection of the bimorph. Tip-surface compliances between 5 and 200 N/m were measured during STM operation. It is possible to use the compliance signal for operating the microscope's feedback loop. Stable feedback loop operation can be achieved for tip-surface distances up to about 200 nm. By operating the microscope in this constant compliance mode, surfaces of arbitrary conductance can be imaged. For conductive surfaces the tunnelling current can be recorded simultaneously. On a Nb3Sn film conducting and isolating patches were detected using this method.
