A team at the University of Calgary has taken a queue from the mosquito and made a wrist based diabetic blood testing device. This autonomous tester will “bite” at set periods throughout the day taking blood sugar readings. Besides monitoring glucose levels this sort of technology could one day be used for DNA testing or cancer screening. Yes, that is an Adafruit OLED display.
Today, the prototype consists of two parts: a reusable watch-like top consisting of the battery, LED display, actuator and various other components, and a disposable bottom cartridge equipped with needle and test strip. The whole prototype is small enough to sit on the wrist and, more importantly, the penetrating needle reaches a capillary under the skin every single time, says Mintchev.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
