Implanted Device Warns of Transplant Rejection
November 14, 2023 | Terry Sharrer
“A tiny bioelectronic device surgically placed upon a transplanted kidney can detect warning signs of organ rejection up to three weeks earlier than current methods, a study in rats suggests. The wireless technology, which is smaller than a fingernail and about the width of a human hair, uses thermal changes as biophysical surrogates of rejection. An ultra-thin, stretchable thermal sensor continually tracks kidney temperature and thermal conductivity, which are used respectively as surrogate markers of organ inflammation and perfusion. When the temperature changes, an alert is sent to a smartphone or tablet, the researchers report in the journal Science.” MORE
