Current Recycling in Multiple Linear Regulating
Power Supplies
The Technology
Neurostimulation in implanted medical devices requires a
high voltage at the implanted electrodes. A new current recycling technology
developed at the UNSW for multiple linear regulating power supplies reduces
power losses associated with generating internal low-voltage implant supply
voltages for powering implant electronics
This innovation can deliver extended battery life or
alternatively a smaller battery size for comparable battery life. These
advantages become more valuable as implantable medical devices become smaller
and more sophisticated.
Key Benefits
The technology has the potential to lead to improved battery
life and performance in implanted medical devices such as cochlear implants,
vision prosthesis, deep brain stimulators, artificial pacemakers and functional
electrical stimulators, where large stimulation voltages are required and where
both volume and power use of a device is restricted.
Reduction of power consumed by implant electronics is
potentially 50% or higher, depending on architectures and power load profiles,
resulting in increased life of the battery powering the device.
The new power supply technology would not result in an
increased manufacturing cost and is suitable for any battery powered device
where high-voltage actuation is needed.
Investment Opportunity
NSi is seeking licensees to develop industry-specific
applications for the UNSW technology in a range of jurisdictions and fields of
use.
