Smart Engineering, Driven By Consumer Needs
Smartphones and tablets that let you diagnose medical conditions and click thermal images... what next?
By Anagha P.
Smartphones, laptops and tablets have now become integral parts of our lives. This has influenced the engineering community too. We are noticing engineers aggregating specialised tools with consumer devices like personal computers (PCs), laptops, tablets and smartphones, to achieve great and useful purposes. Here are a few interesting examples of how consumer devices are being leveraged to increase the reach of technology and make our lives easier.
Smart diagnoses Started in 2009, CellScope is a project by UC Berkeley's Fletcher lab that works on using the cameras of smartphones and tablets to collect images and videos for scientific, educational and medical purposes.The team adds optics, illumination and hardware automation to mobile phone and tablet cameras to create mobile microscopes and diagnostic solutions. They also develop custom software for each mobile microscope application to coordinate image collection, annotation, data management, Web connection and automated image analysis.
3D-printed fight against parasites: Named as CellScope Loa, this small 3D printed box equipped with a high-resolution lens and an Arduino microcontroller board, is a complete diagnostic solution that uses a single drop of blood to automatically detect and quantify loa loa, the parasite that causes Loa loa filariasis (eye worm) disease. With the help of of a high-resolution lens placed directly under the phone camera, the motion sensor in the device detects the wriggling movement of loa loa worms in the blood. The Arduino processes this information and sends it to the smartphone app via Bluetooth. This technology would help control, and eventually eradicate this and other diseases in Africa and other parts of the world where proper healthcare facilities are not available.

Detecting ear infections: According to statistics, five out of six children have at least one ear infection by the time they are three years old. Such infections are usually detected by doctors using a device called an otoscope or auriscope. Prototyped in the UC Berkeley lab and manufactured by CellScope Inc., Oto HOME is an iPhone attachment that serves this purpose.
