Handheld Photonic Device Measures Arterial Stiffness

This is an important development, as arterial stiffness is a biomarker for high blood pressure, but there are no reliable ways of measuring it without a cardiologist bearing special equipment. The new device looks like a blow dryer, but it emits low powered laser beams that work with a specially designed silicon photonics chip to detect extremely slight movements of the skin above an artery. To use the device, the operator, who shouldn't need much training, simply points it at one of the ...
