SEOUL, April 6 (Korea Bizwire)A South Korean research team is drawing attention after developing a suture thread-type measuring sensor that can be implanted in the body.

A joint research team from the Daegu Gyeongbuk Institute of Science and Technology and the Swiss Federal Institute of Technology Zurich announced on Monday the development of a suture thread-type flexible strain sensor that can not only be implanted in the body without causing side effects, but also be employed to stitch up the site of the surgery.

To monitor the change and motion of body tissues under rehabilitation, a variety of medical imaging technologies such as MRI, CT and ultrasonic waves are used, but real-time monitoring is still a challenge.

To overcome this obstacle, the research team developed the suture thread-type implantable wireless strain sensor using fiber ingredients.

The sensor can be used for surgery despite being an electronic device. Accordingly, it can be effectively fixed in the tissue to monitor it for a certain period of time.

With a passive wireless telecommunication system that requires no battery, the senor can send data wirelessly on a real-time basis.

The research team conducted surgery on a mini pig with a damaged Achilles tendon using the newly-developed sensor. After the surgery, the suture and fixation were completed effectively, with the researchers able to monitor the motion of the tissue in real time.
