Coming soon: the Internet of the Body
Fussenegger sees several advantages in this latest development. “Our implant could be connected to the cyber universe,” he explains. Doctors or patients could use an app to intervene directly and trigger insulin production, something they could also do remotely over the internet as soon as the implant has transmitted the requisite physiological data. “A device of this kind would enable people to be fully integrated into the digital world and become part of the Internet of Things – or even the Internet of the Body,” Fussenegger says.
When it comes to the potential risk of attacks by hackers, he takes a level-headed view: “People already wear pacemakers that are theoretically vulnerable to cyberattacks, but these devices have sufficient protection. That’s something we would have to incorporate in our implants, too,” he says.
As things stand, the greatest challenge he sees is on the genetic side of things. To ensure that no damage is caused to the cells and genes, he and his group need to conduct further research into the maximum current that can be used. The researchers must also optimise the connection between the electronics and the cells.
And a final hurdle to overcome is finding a new, easier and more convenient way to replace the cells used in the implant, something that must be done approximately every three weeks. For their experiments, Fussenegger and his team of researchers attached two filler necks to their prototype in order to replace the cells; they want to find a more practical solution.
Before their system can be used in humans, however, it must still pass a whole series of clinical tests.
