摘要： A high frequency ultrasound analog beamformer comprises a linear array of surface acoustic wave (SAW) devices formed on a single crystal piezoelectric substrate, such as a PMN-PT single crystal piezoelectric substrate. Each SAW device comprises ultrasound input and output electrode structures separated by a variable delay structure. The beamformer further comprises a delay controller operably connected to each variable delay structure to control the delay of each SAW device to dynamically focus signals received at each input electrode.

摘要： An implantable bone-conduction hearing actuator based on a piezoelectric element, such as a unimorph or bimorph cantilever bender, is described. Unlike other implantable bone conduction hearing actuators, the device is subcutaneous and once implanted is entirely invisible. The device excites bending in bone through a local bending moment rather than the application of a point force as with conventional bone-anchored hearing aids.

摘要翻译： 描述了基于诸如单压电晶片或双压电晶片弯曲机的压电元件的可植入骨传导听力致动器。 与其他植入式骨传导听力致动器不同，该装置是皮下的，一旦植入就完全不可见。 该装置通过局部弯矩激发骨中的弯曲，而不是像常规骨锚固助听器那样施加点力。
