Abstract
Nerve stimulation is a rapidly developing field, demonstrating positive outcomes across several conditions. Despite potential benefits, current nerve stimulation devices are large, complicated, and are powered via implanted pulse generators. These factors necessitate invasive surgical implantation and limit potential applications. Reducing nerve stimulation devices to millimetric sizes would make these interventions less invasive and facilitate broader therapeutic applications. However, device miniaturization presents a serious engineering challenge. This review presents significant advancements from several groups that have overcome this challenge and developed millimetric-sized nerve stimulation devices. These are based on antennas, mini-coils, magneto-electric and opto-electronic materials, or receive ultrasound power. We highlight key design elements, findings from pilot studies, and present several considerations for future applications of these devices.
期刊介绍:
Neural Regeneration Research (NRR) is the Open Access journal specializing in neural regeneration and indexed by SCI-E and PubMed. The journal is committed to publishing articles on basic pathobiology of injury, repair and protection to the nervous system, while considering preclinical and clinical trials targeted at improving traumatically injuried patients and patients with neurodegenerative diseases.
