The application of electrical engineering principles to biology and medicine is termed as Bioelectronics. It helps in creating novel advanced devices or processes for the inhibition, diagnosis, and treatment of disease, for patient rehabilitation, and for improving health. Interesting applications of Bioelectronics are artificial limbs, humanoids, Pacemakers, Blood Glucose Meter, Biosensors. The next revolutionary development is to produce hybrid materials that interface with natural or synthetic cellular structures with nanoscale electronics to improve human health, impact energy, and to sustain the environment. Bioelectronic research discovers the usage of conductive polymers, quantum dots, photonic dyes, organic semiconductors, carbon nanotubes, graphene, gold nanoparticles, and microfluidic materials for applications in bioimaging, wearable electronics, biosensing and implantable electronics (sensors and electrodes).
