Abstract: A flexible detection/test tape includes a first flexible conductive layer, and a second flexible conductive layer positioned opposite the first conductive layer. A plurality of at least one of sensors, actuators or transducers are positioned between and are bonded to the first flexible conductive layer and the second flexible conductive layer. An insulative material is inserted around the plurality of at least one of the sensors, actuators or transducers. An electrical contact network connects to the first flexible conductive layer and the second flexible conductive layer, whereby power and control signals are provided to the flexible detection/test tape. In an alternative embodiment, a method for producing a detection/test tape includes depositing a material onto a surface of at least one first substrate to form a plurality of element structures. Electrodes are deposited on a surface of each of the plurality of element structures, and the element structures are bonded to a second substrate, where the second substrate is conductive or has a conductive layer, and the second substrate is carried on a carrier plate. The at least one first substrate is removed from the element structures and second side electrodes are deposited on a second surface of each of the plurality of element structures. An insulative material is inserted around the element structures to electrically isolate the two substrates used to bond the element structures. A second side of the element structures is then bonded to another substrate, where the other substrate is conductive or has a conductive layer. Thereafter, the carrier plate carrying the second substrate is removed.

Abstract: A method of producing at least one piezoelectric element includes depositing a piezoelectric ceramic material onto a surface of a first substrate to form at least one piezoelectric element structure. Then an electrode is deposited on a surface of the at least one piezoelectric element structure. Next, the at least one piezoelectric element structure is bonded to a second substrate, the second substrate being conductive or having a conductive layer. The first substrate is then removed from the at least one piezoelectric element structure and a second side electrode is deposited on a second surface of the at least one piezoelectric element structure. A poling operation is performed to provide the at least one piezoelectric element structure with piezoelectric characteristics. In another embodiment, a material for a thick film element is deposited onto a surface of a first substrate to form a thick film element structure having a thickness of between greater than 10 nullm to 100 nullm. The at least one thick film element structure is bonded to a second substrate. Thereafter, the first substrate is removed from the at least one thick film element structure using a liftoff process which includes emitting, from a radiation source (such as a laser or other appropriate device), a beam through the first substrate to an attachment interface formed between the first substrate and the at least one thick film element structure at the surface of the first substrate. The first substrate is substantially transparent at the wavelength of the beam, and the beam generates sufficient energy at the interface to break the attachment.

Abstract: In accordance with one aspect of the present invention, a cantilever of a probe-based instrument is deflected by directing a beam of ultrasonic acoustic energy at the cantilever to apply acoustic radiation pressure to the cantilever. The energy is generated by an acoustic actuator. The transmitted beam preferably is focused using a cylindrical lens, providing a beam tightly focused in one dimension and unfocused in a second dimension. In accordance with another aspect of the present invention, a power source such as an RF signal generator is operated so as to spread the spectrum of acoustic radiation on a time scale that is short or comparable to the acoustic roundtrip time. Such a design diminishing the resonance effects and sensitivity to spacing between the cantilever and the acoustic source.

Abstract translation: 根据本发明的一个方面，通过在悬臂处引导超声波能量束来对基于探针的仪器的悬臂进行偏转，以向悬臂施加声辐射压力。 能量由声学致动器产生。 透射光束优选地使用柱面透镜聚焦，提供在一个维度上紧密聚焦的光束，并且在第二维度上未聚焦。 根据本发明的另一方面，操作诸如RF信号发生器之类的电源，以便将声辐射谱扩展到与声学往返时间相比较短或相当的时间尺度。 这种设计降低了共振效应和对悬臂与声源之间间距的敏感性。
