title = "Laser Doppler vibrometry sensors implemented in a silicon photonic integrated circuit for measuring cardiovascular signals on bare skin",
abstract = "Laser Doppler vibrometer (LDV) sensors can measure skin vibrations originating from propagating superficial arterial pulse waves, which can be used to assess arterial stiffness and identify stenosis and heart failure. A key challenge is to get sufficient diffusely reflected power from bare skin in order to avoid the use of a retroreflective patch. Here we report a prototype, enabled by silicon photonics, that can directly measure the vibrations of bare human skin. We demonstrate a resolution better than 10 pm/sqrt(Hz) when the skin surface is placed at the focal plane of the sensing beams. This result holds great promise for the targeted cardiovascular applications.",
