Abstract

Obstructive sleep apnea (OSA) is a disorder with a high prevalence rate that may induce serious complications. Recent progress in the area of hypoglossal nerve stimulation has played a role as an alternative to conventional therapies though, some patients having retropalatal collapse still have not benefitted. Therefore, here we propose a new type of upper-airway stimulation, referred to as the palatal implant system, which recovers the upper-airway patency by electrically stimulating the soft palate. The system consists of two major parts: an implant that stimulates the soft palate through electrodes and an intra-oral device that delivers power and data simultaneously to the implant via an inductive link. Evaluations of the system are conducted in bench-top, in vitro, and in vivo tests to evaluate its feasibility as an OSA treatment, and the potential development of the system is addressed in the discussion section. In the bench-top test, the power efficiency was 12.4% at d = 5 mm and the system could operate up to 8 mm distance in a bio-medium. Data transmission was also successful at distances ranging 2 to 8 mm within an error margin of 10%. The measured CSCc and the impedance magnitude of the electrode were 62.25 mC cm-2 an...Continue Reading

Brain-Computer Interface

A brain-computer interface, also known as a brain-machine interface, is a bi-directional communication pathway between an external device and a wired brain. Here is the latest research on this topic.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
