Over the past few decades, electronics engineers have developed increasingly sophisticated implantable medical devices. Reliably powering some of these devices, however, can be challenging, particularly when they are based on stretchable materials that move along with the body.

Researchers at the Institute for Basic Science (IBS), Seoul National University and other institutions in South Korea recently developed a new wireless power system that could provide energy to soft implantable devices, even when they are stretching or moving. The new system, introduced in a paper published in Nature Electronics, was initially used to develop a cardiac pacemaker, a medical device that uses electrical pulses to control heartbeats.

Large-area electronics (LAE) is an emerging technology for electronic device manufacture, such as printing or large-scale lithography, the process used to create flat panel displays and solar cells. Using LAE processes, engineers could create systems that are large (several square meters squared) and highly flexible; for instance, based on paper or plastic.

Over the past decade or so, many teams worldwide have been working on LAE systems. This has led to the creation of numerous innovative devices, such as large, flexible and sensing artificial skins for robots.

Researchers at Princeton University have recently realized a new wireless system based on LAE technology that can operate at gigahertz frequencies...
