Some of the prototypes on show

Designed by Team MasSpec Pen

MasSpec Pen is a pen-like device that detects cancer cells from non-cancer cells in 10 seconds. When touching a suspected cancer area, the pen sucks up chemicals from the sample for analysis. It is then plugged into a mass spectrometer that produces a chemical fingerprint that tells doctors if they are looking at healthy tissue or cancer.

FingerReader Designed by Augmented Human Lab

FingerReader is a ring-like device that reads printed text out loud simply by pointing at it with the finger, assisting the visually-impaired. The device has a small camera that directs the users ■ ■ towards the text, scans it, and provides feedback — touch or sound — to guide the user’s finger along a line of words, while also generating real-time audio of the text. Whatever the finger ‘sees’ is read out.

Project Circleg Designed by Fabian Engel and Simon Oschwald

Circleg is an affordable prosthetic designed for amputees in developing countries. It is made from recycle plastic using simple production methods. Its modular design makes it easy and inexpensive to customise and repair.

Rehber Designed by Hamza Oza

Rehber helps locate loved ones in the crowds during the annual Haj. It features a wrist band which has a range of five kilometres — much wider and reliable than Bluetooth or Wi-Fi technology. Another wristwatch-type device acts as a locator for the one wearing the band.
