Abstract

This paper presents microelectromechanical-systems (MEMS)-based electromagnetic micro speaker which is powered using micro thermoelectric generator (µTEG) that extracts energy from the human tissue warmth. Electromagnetically actuated micro speaker reduces form factor, power consumption and increase energy efficiency in hearing aid applications. A µTEG uses energy harvesting method to utilize the temperature differences within a human body and ambience to provide the electrical energy for the micro speaker. In this paper a model that includes the micro speaker and micro thermoelectric generator is described with various domain performances. These domains will be coupled where necessary and the model will focus on efficient power and high sound pressure level (SPL).
