Researchers at Pennsylvania State University have created a soft bioelectronic implant designed to help reduce blood pressure without medication. The findings were published in the journal Device.
The miniature implant, about the size of a fingertip, is attached to the carotid artery and stimulates baroreceptors — specialized nerve endings involved in the body’s natural regulation of blood pressure.
The device was produced using 3D printing technology and made from a flexible hydrogel material. Its soft structure allows it to stretch together with surrounding tissues, reducing the risk of vascular damage.
In experiments involving rats, the implant lowered blood pressure by an average of more than 15%. Researchers also reported that after two weeks, surrounding tissues showed no signs of inflammation or damage.
According to the study authors, the technology could become a promising option for patients with resistant hypertension, a condition in which conventional medications are often less effective.
The research team is now preparing for further testing and plans to adapt the implant for potential use in humans.
Earlier studies also suggested that small doses of peppermint oil may help reduce blood pressure.
