In a method for analyzing samples involving the use of a device for analyzing samples, the device for analyzing samples includes at least a movement part through which a sample moves, and a measurement unit that is formed in a middle of the movement part and that measures a value of an ion current when the sample passes through the movement part. The analysis method includes at least a measurement step for measuring the value of the ion current when the sample passes through the movement part, and a determination step for determining a change over time in a quantity of ions from the value of the ion current measured in the measurement step. The quantity of ions includes a quantity of ions that have leaked from the sample during movement of the sample through the movement part.

An artificial sensory epithelium () to be embedded in a cochlea () of a patient includes a piezoelectric film () and multitude microelectrodes (), (), . . . arranged on the cochlea. The piezoelectric film is arranged along a basilar membrane () in the cochlea. A portion of the piezoelectric film that corresponds to a portion of the basilar membrane that is induced to vibrate by sound waves coming from outside the cochlea vibrates. A microelectrode of the microelectrodes that is arranged on the portion of the piezoelectric film provides electric stimuli to spiral ganglion neurons (). The artificial sensory epithelium preferably includes a support member () configured to support the piezoelectric film and be fixable in the cochlea.
