Sweat Sensor Brings Wow to Biometrics #WearableWednesday


I remember hearing some chatter about sweat analysis in the wearable world a few years ago, so I’m happy to find this report on Wareable about a sensor finally being developed. The team behind the device is a collaboration between University of California Berkeley and the Stanford University School of Medicine, joining chemical and electrical engineering. The device itself is an array of sensors on a board, but there is also a flexible circuit which is the piece coming into contact with the perspiration. Some of the data that can be monitored includes skin temperature, glucose, lactate, sodium and potassium. The great part is they’ve included wireless capability, so the data can be seen on a phone.

The device can be easily placed in a fitness tracker style band or sweat band, making use possibilities huge. Medically you could check levels of certain medications and from a sporting standpoint you could look at hydration. They believe it may even replace blood tests in certain instances, which would be great since needles are not my friends. It appears that this will lead to even more research on sweat and stress on the body throughout the day. What effect will different exercises, environments or diets produce? Check out the team’s paper over at Nature for more detail and implications. It’s an exciting world, and that just backs up why microcontrollers get me so excited—it’s the sensors and connectivity. We are adding more science to our everyday life, and it is allowing us to make better decisions. If you haven’t ever worked with sensors before, a fun way to get started is with the FLORA Sensor Pack. It includes our stitchable FLORA microcontroller and a bunch of sensors to detect changes in the environment. You can look at color, light, movement and location. Plus, you can attach NeoPixels in your project and have them react in certain colors to these conditions. Transform regular clothing into sensing fashions you’ll have fun wearing. Then you’ll just have to face your friends asking, “can you help me make one?”


Flora breadboard is Every Wednesday is Wearable Wednesday here at Adafruit! We’re bringing you the blinkiest, most fashionable, innovative, and useful wearables from around the web and in our own original projects featuring our wearable Arduino-compatible platform, FLORA. Be sure to post up your wearables projects in the forums or send us a link and you might be featured here on Wearable Wednesday!

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 @
