Implantable biomedical devices — like pacemakers, insulin pumps and neurostimulators — are becoming smaller and utilizing wireless technology, but hurdles remain for powering the next-generation implants. A new wireless charging device developed by Penn State scientists could dramatically improve powering capability for implants while still being safe for our bodies, the researchers said.

Modified soft material promises better bioelectronics, researchers say

Soft bioelectronic devices hold potential for many advances in the health care field, but researchers have faced hurdles in identifying materials that are biocompatible while still maintaining all necessary characteristics to operate effectively. A team co-led by Penn State researchers has now taken a step toward achieving such a material, modifying an existing biocompatible material to conduct electricity efficiently in wet environments, as well as send and detect ionic currents within biological media.

Their results were published in the journal Matter.

On a cold, sunny day, you’re driving on a rural road, surrounded by snow-covered fields. In an instant, your eyes process the scene, picking out individual objects to focus on — a stop sign, a barn — while the rest of the scene blurs in the periphery. Your brain stores the focused and blurred images as a memory that can be pictured in your mind later, while sitting at your desk.
