A new system that that wirelessly charges internal implants and wearables could be about to make life easier for patients with conditions such as epilepsy or diabetes.

MagLense is a breakthrough product providing wireless power transfer to internal implants and wearables for more comfortable charging. The system, developed by Cambridge Consultants, provides flexible, efficient and safe wireless power transfer in a simple and user-friendly way.


Currently, users spend four to six hours per cycle charging their implant batteries. The new product does not need precise alignment, and can be used regardless of body shape or size of the consumer.

By contrast, MagLense facilitates wireless charging of smart implants from power sources up to half a metre away, giving the patient freedom of movement, or the ability to sit in a comfortable position during charge. Through self-calibration, MagLense delivers the optimum power for different implants locations and orientations, solely targeting the desired implant.

“This is a real breakthrough, addressing one of the core weaknesses in today’s implant design and solving many of the current clinical and patient challenges,” said Dr. Arun Venkatasubramanian, head of implanted connectivity at Cambridge Consultants.

“By using a power source completely separate from the body, and only when needed, a patient’s day-to-day routine will be transformed and their quality of life drastically improved. This is the latest example of how our unique combination of skills in areas as diverse as wireless communications, medical technology and consumer devices can result in truly world-class innovations that really make a difference to people’s lives.”


Those who could benefit from the development suffer from a wide range of chronic and episodic conditions such as epilepsy, diabetes, obesity and depression. The technology could facilitate more widespread use of micro implants in inaccessible parts of the body.

Further potential could see the approach used for consumer wearable devices, allowing charging of phones and other technology while in use.

“MagLense addresses one of the ‘holy grails’ of smart implant design” added John Genova, the company’s head of smart implant development. “Efficient, safe and targeted through-body power delivery is a critical missing component for next generation implants. Our technology enables a level of performance that opens the door for a whole new generation of implanted therapeutics.”
