Engineers at Tufts invented a thread that wirelessly collects real-time diagnostic data when sutured into tissue. The thread-based diagnostic platform could be an effective substrate for a new generation of implantable diagnostic devices and smart wearable systems. The research was published in the journal Microsystems & Nanoengineering and has been featured in a number of media outlets, including The Economist, WBUR, IEEE Spectrum, and STAT.

Authors included Tufts alumni Pooria Mostafal and Kyle Alberti, who were PhD students at the time of the research; Assistant Professor Qiaobing Xu of the Department of Biomedical Engineering; and Associate Professor Sameer Sonkusale of the Department of Electrical and Computer Engineering, alongside colleagues from Harvard Medical School’s Biomaterials Innovation Research Center, the Harvard-MIT Division of Health Science and Technology, and Harvard University’s Wyss Institute for Biologically Inspired Engineering.
