Bioelectronics often involves the sensing and control of cellular function, Bioelectronics is a field of research in the convergence of biology and electronics. Bioelectronics is used to help improve the lives of people with disabilities and diseases. For example, the glucose monitor is a portable device that allows diabetic patients to control and measure their blood sugar levels.Electrical stimulation used to treat patients with epilepsy, chronic pain, Parkinson's, deafness, Essential Tremor and blindness.Magnuss Berggren and colleagues created a variation of his OEIP, the first bioelectronic implant device that was used in a living, free animal for therapeutic reasons. It transmitted electric currents into GABA, an acid. A lack of GABA in the body is a factor in chronic pain. GABA would then be dispersed properly to the damaged nerves, acting as a painkiller. Vagus Nerve Stimulation (VNS) is used to activate the Cholinergic Anti-inflammatory Pathway (CAP) in the Vagus Nerve, ending in reduced inflammation in patients with diseases like arthritis.
