Dissolvable Battery to Power Transient Implantable Devices
http://www.medgadget.com/wp-content/uploads/2016/08/dissolvable-battery.jpg
We’ve seen the development of dissolvable brain implants (http://www.medgadget.com/2016/05/researchers-develop-dissolvable-electronic-brain-implants.html) and other so-called “transient electronics (http://www.medgadget.com/2012/10/dissolvable-transient-electronics-will-be-good-for-your-body-and-the-environment.html)” that are slowly washed away and disappear some time after implantation. One thing missing but required for these devices to be fully implantable and dissolvable is a battery that does the same at about the same rate. **w researchers at*Iowa State University are reporting on a lithium-ion battery that provides about 2.5 volts of power before disintegrating in water in about thirty minutes.
Though the power produced by this battery is only sufficient*to run*a calculator for about fifteen minutes, the proof-of-concept is e**ugh to point to great potential for diag**stic and therapeutic devices that don’t require a visit back to the doctor for explantation. In particular, brain implants would probably benefit the most since their removal can be particularly challenging and dangerous.
From the study:
The battery takes advantage of a close variation of the active materials used in conventional Li-ion batteries and can achieve and maintain a potential of >2.5 V. All materials are deposited form polymer-based emulsions and the transiency is achieved through a hybrid approach of redispersion of insoluble, and dissolution of soluble components in approximately 30 min.
