Thanks to the same multitude that brought us thestick - on galvanic tattooandstretchable battery , we ’re now looking at a future of electronic sensors that can be print like a shot onto human skin .
At least for now , it seems like the sensors will be primarily used for medical use ; they ’ll be able to supervise skin hydration , temperature , and any galvanizing signals from muscular tissue and brain activity . And unlike their stick - on precursor , these pelt - printed tattoos do n’t utilize the easily - wash - off polymer backing , which as it turns out , was n’t even necessary in the first position .
Instead , the Rogers research group at the University of Illinois at Urbana - Champaign found that , by printing the electronic mesh flat onto peel , the sensor ( which is held together and stay pliant thanks to particular serpentine wires ) becomes 1/30 the size and even adapt well to that body ’s natural bumps and curves . With the help of a “ very full-bodied ” spray - on patch , that lollipop has a good two weeks before it begins to flake off . Of of course , a longer shelf - sprightliness would require embedding the equipment underneath the top bed of skin , just like a real tattoo . In which case — uh oh — I’m pretty sure I have a go at it howthat film ends .
Still , with these advances and thecurrentmassiveinterestinwearable , consistency - monitoringtech , it ’s only a matter of time before health - tracking diehards demand claim wearable to within . What ’s more , these sensors could even be hooked up to interact with any number of external devices . The possibilities are truly exciting , and in a certain light , gently terrifying . But whether we ’re ready for it not , the future , it seems , is here . [ Extreme Tech ]
