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.

One double-helix strand of DNA could extend six feet, but it is so tightly coiled that it packs an entire sequence of nucleotides into the tiny nucleus of a cell. If that same DNA was instead split into two strands and divided into many, many short pieces, it would become trillions of uniquely folded 3D molecular structures, capable of bonding to and possibly manipulating specifically shaped molecules — if they’re the perfect fit.

The ability to regenerate and pattern blood vessels, the literal lifelines extending deep into soft tissues, remains an elusive milestone in regenerative medicine. Known as tissue revascularization, stimulating blood vessel growth and pattern formation in damaged or diseased tissues could accelerate the field of regenerative medicine, according to Penn State researchers.

Acoustic waves may be able to control how particles sort themselves. While researchers have been able to separate particles based on their shape — for example, bacteria from other cells — for years, the ability to control their movement has remained a largely unsolved problem, until now. Using ultrasound technology and a nozzle, Penn State researchers have separated, controlled and ejected different particles based on their shape and various properties.

Researchers at Penn State are designing a new wireless rechargeable battery for biomedical electronics, such as cardiac pacemakers, that will allow them to be charged and managed without the need for invasive surgery.

UNIVERSITY PARK, Pa. — For wearable electronics to live up to their promise for health care monitoring, they need to do at least two things: transform from rigid to soft to accommodate changing structural needs, and heal their own normal wear-and-tear. With the help of liquid metal and specialized polymers, researchers have developed sensors that can do both.

UNIVERSITY PARK, Pa. — For mere dollars, a Penn State-led international collaboration has fabricated a self-powered, standalone sensor system capable of monitoring gas molecules in the environment or in human breath. The system combines nanogenerators with micro-supercapacitors to harvest and story energy generated by human movement.
