The Esteem hearing implant by Envoy Medical is a fully implantable system that uses piezoelectric transducers. This device uses the eardrum as the microphone. The mechanical signal is detected by a piezoelectric transducer at the head of the incus (the sensor) and converted to an electrical signal that is amplified, filtered, and converted back to a vibratory signal. The processed vibratory signal is then delivered by another piezoelectric transducer (the driver) to the stapes capitulum.
恩沃伊医疗公司的Esteem听力植入物是一种使用压电换能器的完全可植入系统。该设备将耳膜用作麦克风。机械信号由砧骨头部的压电换能器（传感器）检测到，并转换为电信号，该电信号经过放大、滤波后再转换回振动信号。然后，经过处理的振动信号由另一个压电换能器（驱动器）传递到镫骨头。
