The ultimate human-gadget-interface?
How amazing is this? The ultimate in HGI – human-gadget-interface?
Thanks to Sue P for flagging this one, an article about scientists creating biological tissue with embedded wiring.
It involves a collaboration between MIT, Harvard, MIT and Boston Children’s Hospital, where researchers are combining artificial tissue with nanometer-scale electronics…

The researchers have created a self-supporting scaffolding of nanowires, each about 80 nanometers in diameter, bunched up in a chaotic, porous configuration that has been likened to cotton candy and coated with a biocompatible material. Cell cultures are then deposited in the gaps between the nanowires and grow to form a single structure with the signal-carrying nanowires. With this technology, researchers can work at the cellular scale much more effectively, without damaging the cells and with the capability to observe cells from anywhere within the tissue.
In preliminary experiments, heart and nerve cells were grown inside the nanostructured scaffolding. Using the networks of nanowires, the researchers could detect the cells’ electrical signals generated deep within the tissues and measure how they responded to cardio- or neurostimulating drugs. Then, they constructed bioengineered blood vessels with embedded nanowiring networks and showed that they could measure changes in pH, which normally happen in response to inflammation.
