This Ring Could Be Used to Sniff Out a Bomb #WearableWednesday
Here is a handy piece of wearable tech for detecting explosives. Maybe we are getting a little closer to being able to keep our shoes on at the airport. Via Alphr:
A new wearable device can detect chemical or biological threats, from explosives to organophosphates – toxic substances used in insecticides.
Appearances aside, the ring shows promise for what the future could hold. It works using a hydrogel cover, which chemicals will diffuse through. When they hit a circuit board underneath, changes in the current are recorded and sent to a laptop using Bluetooth LE.
By monitoring how different threats cause different changes in current, the team could work out how to then identify those chemicals based on the activity of the ring.
“Most wearable [devices] measure vital signs for sport or health,” Joseph Wang, a nanoengineer at UC and co-author of the paper, told The Register. Instead, his team wanted to use technology to spot signs of biohazards. Wang and the team expect it to be used in dangerous circumstances, and the reseach was partly funded by the US Defense Threat Reduction Agency Joint Science and Technology Office for Chemical and Biological Defense.
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!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
