Would you spit on your iPhone? Researchers at the Korea Advanced Institute for Science and Technology are currently developing a way to quickly diagnose specific diseases – with an iPhone and saliva. The researchers claim that the touch sensitivity of smartphones with touch screens – such as the iPhone – might have the capability to be used as a diagnostic chip. According to an article in Forbes, the institute’s “innovation harnesses a touchscreen’s ‘capacitive sensitivity,’ its ability to sense a fingertip’s electrical charge. The iPhone touch screen’s sensitivity extends far beyond that needed to sense a finger touch or tap, leading researchers to speculate what else it could detect, such biomarkers in bodily fluids signifying the presence of disease.” Read more about this story…
