Talk: Hearing aid energy sources then, now and in the near future

The challenges in powering still more power hungry hearing aids with miniature energy sources, mainly batteries, are described by some history and examples. An overview of future technology for hearing aid energy sources is provided and examples are explained. Primary battery (non-rechargeable) technology like zinc air (ZnAir) and secondary technologies like nickel metal-hydride (NiMH), silver zinc (AgZn), are compared with respect to capacity, energy density, cycle life and power (“rate”) capability.
