Tiny, implantable device uses light to treat bladder problems

Via Washington University in St. Louis | January 2, 2019

A team of neuroscientists and engineers has developed a tiny, implantable device that has potential to help people with bladder problems bypass the need for medication or electronic stimulators.

The team — from Washington University School of Medicine in St. Louis, the University of Illinois at Urbana-Champaign, and the Feinberg School of Medicine at Northwestern University in Chicago — created a soft, implantable device that can detect overactivity in the bladder and then use light from tiny, biointegrated LEDs to tamp down the urge to urinate.

The device works in laboratory rats and one day may help people who suffer incontinence or frequently feel the need to urinate… Continue reading.

John Rogers Receives 2019 Benjamin Franklin Medal

Via Northwestern University | December 10, 2018

Northwestern Engineering’s John A. Rogers has received the 2019 Benjamin Franklin Medal in Materials Engineering from The Franklin Institute, one of the oldest centers for science education and development in the country.

Rogers is the Louis Simpson and Kimberly Querrey Professor of Materials Science and Engineering and professor of biomedical engineering in the McCormick School of Engineering, professor of neurological surgery in the Feinberg School of Medicine, and director of the Center for Bio-integrated Electronics. He also is a member of the Simpson Querrey Institute, and has affiliate appointments in chemistry, mechanical engineering, and electrical engineering and computer science.

The Franklin Institute cited Rogers “for pioneering the engineering of flexible and stretchable electronic systems for e-health and exploratory neuroscience… Continue reading.

World’s Smallest Wearable Device Warns of UV Exposure, Enables Precision Phototherapy

Via Northwestern University | December 5, 2018

The world’s smallest wearable, battery-free device has been developed by Northwestern Medicine and Northwestern Engineering scientists to measure exposure to light across multiple wavelengths, from the ultra violet (UV) to visible and even infrared parts of the solar spectrum. It can record up to three separate wavelengths of light at one time.

The device’s underlying physics and extensions of the platform to a broad array of clinical applications are reported in a study published December 5 in Science Translational Medicine. These foundational concepts form the basis of consumer devices launched in November to alert consumers to their UVA exposure, enabling them to take action to protect their skin from sun damage.

When the solar-powered, virtually indestructible device was mounted on human study participants, it recorded multiple forms of light exposure during outdoor activities, even in the water. The device monitored therapeutic UV light in clinical phototherapy booths for psoriasis and atopic dermatitis, as well as blue light phototherapy for newborns with jaundice in the neonatal intensive care unit. It also demonstrated the ability to measure white light exposure for seasonal affective disorder…. Continue reading.

Researchers Demonstrate First Example of a Bioresorbable Electronic Medicine

Via Northwestern Engineering | October 8, 2018

Researchers at Northwestern University and Washington University School of Medicine have developed the first example of a bioresorbable electronic medicine: an implantable, biodegradable wireless device that speeds nerve regeneration and improves the healing of a damaged nerve.

The collaborators — materials scientists and engineers at Northwestern and neurosurgeons at Washington University — developed a device that delivers regular pulses of electricity to damaged peripheral nerves in rats after a surgical repair process, accelerating the regrowth of nerves in their legs and enhancing the ultimate recovery of muscle strength and control. The size of a dime and the thickness of a sheet of paper, the wireless device operates for about two weeks before naturally absorbing into the body.

The scientists envision that such transient engineered technologies one day could complement or replace pharmaceutical treatments for a variety of medical conditions in humans. This type of technology, which the researchers refer to as a “bioresorbable electronic medicine,” provides therapy and treatment over a clinically relevant period of time and directly at the site where it’s needed, thereby reducing side effects or risks associated with conventional, permanent implants… Continue reading.
