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.
