Faster in-body electronics gives better life

Telehealth gives options to significantly improve patient care and cut health costs. To come up to the expectations, however, in-body electronics has to be faster and far less energy-consuming.

Atila Alvandpour, a LiU Professor of Electronic devices, works on the solution in a new research project funded by the Swedish Governmental Agency for Innovation Systems, Vinnova.

“We want to make use of our progress in new areas, find applications that can help people to a better life”, says Professor Alvandpour, who has a background at Intel Research Laboratory at Portland, Oregon.

His and his fellow researchers’ reputation as specialists on low-effect, high-speed circuits attracted interest from Zarlink Semiconductor, a medtech company supplying systems to e.g. pacemakers and implant defibrillators.

Such devices are today possible to control wirelessly from a close distance outside the body. A prerequisite to reach further out is to increase the bandwidth and radically reduce the power consumption. The goal is to build devices that won’t need new batteries during the patient’s lifetime.

The major challenge is to design chip architectures that can handle those ex­tremely weak currents­—in the magnitude of nano-ampères.
