Bioelectronics have been gaining popularity in recent years due to their potential use in the field of neurorehabilitation. The aim is to use these technologies to help individuals recover from various neurological conditions such as stroke, spinal cord injury, and traumatic brain injury. The basic principle behind bioelectronics is to use electrical/optical stimulation to activate neurons in the brain and promote functional recovery. One example of bioelectronics use in neurorehabilitation is through the development of brain-computer interfaces (BCIs). BCIs are computer systems that use electrodes to detect and interpret electrical signals generated by the brain. These signals can then be used to control external devices such as robotic limbs, exoskeletons, and computer interfaces. The hope is that BCIs will help individuals with paralysis or other conditions regain movement and control over their limbs.

While bioelectronic devices hold great promise in revolutionizing medicine and healthcare, they also face numerous challenges that must be overcome (you can add some references from above here). This includes improving the longevity and safety of these devices, ensuring their ethical use, and ensuring their compatibility with the human body and the environment.
