your phone at home again? A solution is at hand: make sure it is with you at
all times by having it implanted in your arm.
But given the opportunity, would you want
your gadget to be a permanent part of you? The question may need answering
sooner than you think.
Researchers at Autodesk, a software company in Toronto, Canada, checked to
see whether the methods we currently use to interface with our gadgets work
when the device is implanted in human tissue. The answer was a resounding
"yes".
A button, an LED and a touch sensor all
functioned appropriately when embedded under the skin of a cadaver's arm. The
team was even able to communicate transcutaneously using a Bluetooth connection
and charge the electronics wirelessly.
Would anyone want a piece of consumer
electronics inside their body? There is something intrinsically creepy about
the idea. Plus there is a risk that the device could malfunction and need to be
removed, or that it could infect the surrounding tissue, not to mention the
dystopian vision of a society in which our phones become tracking devices that
we can never be free of.
Yet there are reasons for thinking that the
cyborg future will come to be. The team, who worked with University of Toronto
anatomist Anne Agur, says that medical risks such as infection need
to be better understood before a device can be implanted into a living person.
But it is a problem that manufacturers of existing implants, such as stents and
replacement hips, have successfully tackled.
There are also clear benefits to implanted
electronics. "The device is always there," says Holz. "You
cannot lose it." And implants provide new interface methods. A gadget
similar to a smartphone could provide a calendar alert by means of a gentle
sub-skin vibration, for example.
And that creepy feeling? It is a common
reaction now, but may lessen as people become familiar with the technology. The
idea of using a machine to assist a human heart was once deemed unnatural, for
example, but the insertion of a pacemaker is now a routine procedure.
