Tendon and ligament injuries are common, especially in sports. These injuries often need surgery to fix them. But what happens after the surgery? This is where things get tricky. Doctors need to keep an eye on how the tissue is healing. If the tissue is under too much stress, it can cause problems like the graft getting injured again or loosening.

Imagine a tiny sensor that can be put on a suture, or stitch, during surgery. This sensor can measure how much the tissue is stretching and send that information wirelessly. It's like having a tiny nurse checking on the healing process from the inside. The sensor is flexible and can handle a lot of stretching without breaking. It can detect even the smallest changes in strain, down to 0. 25%.

This sensor can be used in complex surgeries, like fixing a torn ligament in the knee. It can tell the difference between normal stretching and something more serious, like the graft getting injured again or loosening. Animal tests showed that the sensor works well and is safe for the body.

But here's where things get interesting. This sensor could be a game-changer for testing new implants before they're used in humans. It could also help doctors keep an eye on any problems that might come up after surgery. But there are still questions to be answered. How well will it work in humans? How long will it last? And how much will it cost?

Think about the bigger picture. This technology could change how we approach tendon and ligament injuries. It could make surgeries safer and more effective. But it's not just about the technology. It's about the people who will benefit from it. It's about giving athletes a better chance to recover and get back to their sport. It's about helping anyone who's had a tendon or ligament injury live a better life.

But we need to think critically about this. Is this technology really necessary? Or is it just another step towards more invasive procedures? And what about the cost? Will it be affordable for everyone who needs it? These are questions we need to ask as we move forward with this technology.
