Humans may be one step closer to becoming cyborg . research worker have spring up a indulgent , flexible contact lens that monitor glucose level in rent and tells the wearer if they are hyperglycemic . The team hope the equipment will one day be used by those with diabetes so that they will no longer have to prick themselves to supervise their origin sugar level .
The contactshave a lilliputian glucose sensing element and guide light integrate into them . An antenna then picks up radiofrequency sign from a sender and converts that to electrical energy , which is fed to a light that shines unripe . When the sensor registers that the glucose stratum in one ’s bust has topped a set limitation , it cuts the power to the LED and the light goes off . The LEDs are specifically positioned to front outward so that the wearer can not unremarkably see them .
This think of that by calculate in a mirror , anyone wearing the lenses can see when they need to adapt their insulin story . The astute among us will have actualise that it seems a little remaining to have the lens only twist off when glucose levels ascend , and this has not happen by the researchers unnoticed , who saidthey might see if they can invert that mo in the future .
After testing the contact lens on rabbits , and publish their final result inScience Advances , the squad launch no signs that the lens were uncomfortable .
The researchers construct the contact lenses by using flexible , pellucid element whenever possible . Only a few bits of the lens system are not flexible , include the glucose sensing element , which is made from a rigid silicon diggings . However , the squad separated the pad into two pieces and link them with flexible wires to help with that .
Overall , all components in the crystalline lens are 1/100 the thickness of the soft link lens in which they are place . Not only that , but all turn of the technical school that could not be transparent are locate in sections that are over the iris diaphragm where they can not be escort by the wearer . This means that – in hypothesis at least – the user should not be capable to see any of the electronics .
The electron lens are yet to be tested on humans , but the team are fairly confident that they will be successful . Do n’t go rushing to your pharmacy just yet though , as they consider it may take another five years to perfect them in hoi polloi .
