    Abstract

    A multilayer piezoelectric actuator has been evaluated for use in a hearing implant. Its Frequency response was flat up to 20kHz. Initial in-vitro trials gave stapes displacement From stimulation at 3.5V RMS, which is equivalent to that from acoustic stimulation at 90dB SPL below 1kHz, increasing to 120dB at 8kHz. This performance meets accepted clinical specifications.
