Abstract: A layered solid element (100) comprises a ferroelectric layer (2) of a crystalline material Li 1-x (Nb 1-y Ta y ) 1+x O 3+2x-z which has X- or 33°Y-orientation with respect to a substrate (10) of the layered solid element. The ferroelectric layer is grown epitaxially from a buffer layer (1) having of one of the chemical formulae L k Ni r O 1.5·(k+r) + w or L n+1 Ni n O 3n+1+δ , where L is a lanthanide element. Such layered solid element may form a thin-film bulk acoustic resonator and be useful for integrated electronic circuits such as RF-filters, or guided optical devices such as integrated optical modulators.

Abstract: A haptic actuator assembly comprising a haptic actuator and a pre-load device is presented. The haptic actuator is configured to generate a displacement along a first axis, wherein the haptic actuator is a piezoelectric actuator. The pre-load device is adjacent to the haptic actuator and configured to generate a compressive load on the haptic actuator along the first axis. The pre-load device includes a first component and a second component that are disposed on opposing surfaces of the haptic actuator, and are configured to generate a magnetic force that attracts the first component and the second component to each other in order to generate the compressive load on the haptic actuator along the first axis. The first component is a permanent magnet, and the second component is at least one of another permanent magnet, an electromagnet, or a ferromagnetic component that comprises ferromagnetic material.

Abstract: Disclosed is a piezoelectric sensing apparatus, comprising: a plurality of piezoelectric regions, each piezoelectric region including an anode surface and a cathode surface, wherein the plurality of piezoelectric regions are successively connected from the first piezoelectric region to the last piezoelectric region such that between adjacent piezoelectric regions, surfaces of a same polarity are connected, i.e., one anode surface is connected to another anode surface, while one cathode surface is connected to another cathode surface. The piezoelectric sensing apparatus as provided may effectively boost a high-frequency signal while weaken a low-frequency signal, such that an output waveform signal facilitates improving the positioning accuracy.
