Science Drivers

• implantable healthcare
• component testing

NSF Relevance

This is an essential tool for advancing the prototyping of implantable healthcare electronic devices. Implantable devices require a power source. For example, in spinal cord injuries, there are devices that can transmit electrical signals to trigger muscles, bypassing the injury area. Without a power source innovations must stay external, leaving holes in the body that are prone to infection or devices batteries must be surgically replaced. This charging tool is a fundamental element of any advancement in the field of implantable devices.

Integration Guide

To use PM COIL Molecule v12 in your design:
