Bioengineers at Harvard University have managed to grow human tissue around a complex structure of nanowires and transistors, Will Ferguson of the New Scientist reports.
The research, published in Nature Materials, yielded "cyborg flesh" that can monitor and transmit data such as a body's heart rate.
"It allows one to effectively blur the boundary between electronic, inorganic systems and organic, biological ones," lead researcher Charles Lieber told the New Scientist.
The team created a 0.6-inch human blood vessels and were able to monitor its electrical activity in real time, which had never been done before.
