Smartphone Accessory Diagnoses HIV and AIDS
Biomedical engineers at Columbia University have created a smartphone accessory and app that accurately diagnoses HIV and AIDS, and costs under $35 per unit to produce. The palmsized accessory plugs into the smartphone's audio jack as a power source and to transfer data. It processes blood samples in less than 15 minutes, delivering the results to the smartphone app. While still seeking regulatory approval, its makers hope it will slow the spread of disease in Africa and other developing countries.
