Solution


Processed audio jack input signal to calculate blood glucose level.

Used audio jack output signal to generate sine wave to power the device.


Screenshots show the progress of signal over time and calculation of blood glucose level.

Displayed signal is after A2D conversion and noise filtering over a 24 second period.

15.05 kHz output wave was used to power the device.

Challenge


Develop a cross-platform app with user friendly UI for end user of portable battery-less blood glucose monitor that can plug into phone or laptop audio jack.

Solution


Cross platform app developed with UI implemented using OpenGL and Cocos2dx to work across iOS, Android, Windows and Mac OSX.

Signal processing graphs replaced by a simple countdown.

Apps developed for iOS and Android using C++ (with some small modules in Java and Objective C). Single codebase builds app for all platforms.
