Ultrasonic implant manages relieve chronic:
Essential
- 20 million people with chronic pain in France. Consequently,
- Researchers have developed a wireless stimulator induced by ultrasound that manages to block pain in a personalized way. Meanwhile,
- The tests carried out on rodents are very promising. Moreover,
A new hope for the 20 million people with chronic pain in France. Therefore, Researchers from the University of Southern California have developed an ultrasonic implant that manages to block pain signals. Meanwhile, could thus reduce the use of opioids.
The device was presented in an article published in the review Nature Electronicsthe 12 From 2025.
Relief of pain on demand: How does this ultrasonic implant work? – Ultrasonic implant manages relieve chronic
Trying to reduce pain using a stimulator is not new. However, Such devices already exist. However, these are electric and ultrasonic implant manages relieve chronic require bulky batteries. The device developed by researchers and engineers from the Californian establishment is fed by a portable ultrasound transmitter without battery. This allows him to be less bulky on a daily basis.
The wireless and flexible implantable stimulator (UIWI) is attached to the spine. It was designed to transform the ultrasound sent by the transmitter into electrical stimulation. Like other stimulators, this current prevents pain signals from reaching the brain. The new device is also equipped with a system that allows it to continuously monitor brain records. in particular electroencephalogram (EEG) signals, reflecting the patient’s level of suffering. With an AI based on automatic learning. UIWI is capable of identifying and classifying these brain signals in three types of pain (light, moderate and intense) with a precision of 94.8 %.
“Once the level of pain is identified, the portable ultrasound transmitter automatically adjusts the acoustic energy it transmits. ultrasonic implant manages relieve chronic The UIWI stimulator can then detect the propagated energy and convert it into electrical intensity, thus stimulating the spinal cord. This creates a closed loop system which allows personalized. real -time management of pain”specify the authors in their press release.

Ultrasonic implant against pain: tests with encouraging rodents
If the ultrasound implant against pain has not been tested yet on humans, it has been implanted on rodents. During experience. researchers managed to relieve chronic neuropathic suffering from animals caused by both mechanical stimuli (such as a pin bite) and by acute thermal stimuli (infrared heat).
Faced with these very encouraging results, the team plans to continue their research in order to further miniaturize the aircraft. Their objective is to be able to ultimately offer a less invasive establishment, for example with a syringe.

.
“The portable ultrasonic transmitter could also ultrasonic implant manages relieve chronic evolve towards a miniaturized and autonomous device, even to a patch of portable ultrasound, potentially combining imagery and energy delivery capacities for real -time monitoring and targeted stimulation. Future versions could also be controlled by smartphone software, offering personalized even more efficient pain management”add scientists.
