Abstract: This disclosure describes techniques and systems for extracting energy from the endocochlear potential (EP) in animal subjects (e.g., human subjects) and using the extracted energy to operate circuits (e.g., electronic device, sensors, and transmitters). The subject matter of this disclosure is embodied, for example, in a system for extracting energy from an endocochlear potential of an animal, wherein the system includes a pair of electrodes, and a circuit coupled to the pair of electrodes. The circuit includes a boost converter, an energy buffer component configured to receive voltage from the boost converter, a start-up rectifier configured to provide voltage to the energy buffer component, and a control component configured to provide control signals to the boost converter. The power extracted from the endocochlear potential is equal or larger than the quiescent power of the circuit.

Abstract: In one aspect, the disclosure features systems for providing auditory signals to a subject. The systems include a sensor front-end circuit configured to be connected to an acoustic sensor and to convert analog signals received from the acoustic sensor to digital electric signals. The systems further include a sound processor circuit configured to be connected to the sensor front-end circuit and receive the electric signals provided by the sensor front end circuit. The sound processor includes multiple filters that spectrally decompose the received electrical signals into multiple spectral channels during operation of the system. The multiple spectral channels include at least a low frequency channel and a high frequency channel and the sound processor circuit is configured to operate the low frequency channel at a sample rate lower than a sample rate of the high frequency channel.
