The field of smart wearable systems has just gotten a boost thanks to researchers from Tufts University.* A team of engineers has developed a **vel 3-dimensional thread-based diag**stic platform that, when sutured into tissue, collects a range of real-time diag**stic data wirelessly, including pH, glucose levels, temperature, stress, strain, and pressure.* Physical and chemical na**sensors, microfluidics, and electronics integrated into various types of conductive threads, including cotton and synthetic fibers, are connected to a wireless electronic circuit.* The result is a suture that can penetrate tissue, sense various factors in the interstitial fluid, and relay*information to a wireless transmitter affixed to the the skin, which then transfers data to a computer or smartphone.
