Contact lenses that measure blood sugar can be done not only by Google X
With the help of the Thiel Foundation, founded by Peter Thiel, a 22-year-old dropout boy named Harry Gandhi is focusing on contact lenses that measure blood sugar, which coincides with the idea of ​​smart contact lenses in Google X Labs.
His company, Medella Health, was founded in 2013 and the product is still in the prototype stage. The principle is to detect the blood sugar content in the tear by implanting a biosensor in the lens, process the data through a circuit, and use the antenna to transmit the data to another small device, and finally to the terminal containing the Bluetooth, the user can analyze himself based on the App. The data.
In contrast, Google X stealth is built-in tens of thousands of micro-transistors, there are also "thin than the hair" antenna, sent to the user's smart terminal device.
An industry insider who visited Google X mentioned that they intend to use the body's own bio-electric energy, such as electrochemical signals, to power the glasses. But the Medella team gave up on this idea because the electrochemical reactions between humans were too complex and uncontrollable.
It seems that no matter which kind of power supply method, Google X and Medella do not intend to add a heavy battery to the glasses.
Regarding the frequency of blood glucose measurement, Medella products are more suitable for patients with type 2 diabetes, that is, intermittent measurement, just wave your phone in front of you when you need it. Dimensions such as time and place are also recorded during measurement.
Harry did not disclose the time to market, and it is estimated that commercialization is still far away. Relatively speaking, Google X's products are more commercial, because Novartis has obtained the technology license for the smart contact lens, and plans to develop it into a commercial product through its eye care subsidiary Alcon (Alcon).
