In January, the FDA approved a noninvasive bioelectronic treatment for sinus pain. The research study also showed the device can work as a temporary pacemaker and as an interface to the spinal cord and other stimulation sites across the body. First example of a bioelectronic medicine: Biodegradable implant provides electrical stimulation that speeds nerve regeneration. "We engineer the devices to disappear," Rogers said. Living organisms use a sophisticated arsenal of membrane receptors, channels, and pumps to control signal transduction to a … "Before we did this study, we weren't sure that longer stimulation would make a difference, and now that we know it does, we can start trying to find the ideal time frame to maximize recovery," Ray said. Researchers at Northwestern University and Washington University School of Medicine have developed the first example of a bioelectronic medicine: an implantable, biodegradable wireless device that speeds nerve regeneration and improves the healing of a damaged nerve. devices that will enable applications in these areas will impact other vital areas, such as homeland and national security, forensics, and the environment. This nerve sends signals up and down the legs and controls the hamstrings and muscles of the lower legs and feet. The field of bioelectronic devices [] comprises non-invasive wearable devices such as temperature and pressure sensors [2–9], as well as implantable devices such as neural interfaces [10–17] and pacemakers [18, 19].All of these devices have in common the fact that they are built of multiple materials, resulting in multimaterial based bioelectronics devices. When Ray and his colleagues at Washington University identified the need for electrical stimulation-based therapies to accelerate wound healing, Rogers and colleagues at Northwestern went to their toolbox and set to work. This type of technology, which the researchers refer to as a "bioelectronic 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. These findings suggest broad utility, beyond just the peripheral nervous system. Bioelectronics is the application of the principles of electronics to biology and medicine.
