Researchers at Daegu Gyeongbuk Institute of Science and Technology have developed a neuromodulatory interface that stimulates peripheral nerves without batteries.

The technique, developed by a team led by Professor Lee Sang-hoon at the university, creates a device that collects mechanical kinetic energy that is discarded in the body and converts it into triboelectric energy and then combines it to the team’s neural interface technology.
The team developed this technique by studying the urinary bladder pelvic nerves of patients suffering from a neurogenic bladder.
Patients with neurogenic bladder use treatments to stimulate the sacral nerve by inserting neurostimulators into the body. However, the treatment method can become a psychological and economic burden on patients due to its side effects and periodic battery changes.
Professor Lee’s triboelectric nerve stimulation device can collect mechanical kinetic energy from the human body and convert it into triboelectric energy, which induces urinary function of the bladder without the need for a battery.
The developed neuromodulator interface is also flexible and small, reducing the risk of complications and unnecessary nerve stimulation.
“The technique, which uses triboelectric stimulation to controls the pelvic bladder nerve has shown unlimited application potential for the development of a battery-free human implantable nerve stimulator,” Professor Lee said.
