Scenarios are a highlight of our new biomedical engineering programme. In a scenario, all lectures stop and students spend the whole week working on a group project where they solve a biomedical engineering problem. Last week, our second year students worked with Jenny Griffiths to build articles of smart clothing. Their brief was to design and build an item of clothing to monitor a marathon runner’s wellbeing and give an alert to inform the runner and all those around them to prevent injury. Students were encouraged to be creative and develop their own solutions as long as their device met the design brief and was safe.DSC00656
Jenny provided the students with a range of components, mainly centered around the Adafruit Flora wearable arduino. We gave them sensors including temperature and pressure sensors, accelerometers, GPS, UV and light sensors and stretchy conductive rubber. Outputs included buzzers, vibration motors, Bluetooth connectivity and programmable RGB LEDs, but they were only allowed to use up to £40 for materials. The task built upon electronics modules which students took last year, and a clinical engineering module which includes lectures on transducers which the students are taking at the moment.
We put the students into random groups and let them loose!
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.
