Tufts University researchers have created a thread-based diagnostic platform to provide real-time health data for implanted devices and wearables.
Thread-integrated nano-scale sensors, electronics and microfluidics can be sutured through multiple layers of tissue . Measures of tissue health (pressure, stress, strain and temperature), pH and glucose levels are collected. Results are transmitted wirelessly.
The system can be used to determine how a wound is healing, whether infection is emerging, or whether the body’s chemistry is out of balance.
The three-dimensional platform can conform to organs, wounds or orthopedic implants. Previously, substrate structures for implantable devices have been two-dimensional, limiting their use to flat tissue, such as skin.
