Last week finalists of the Nokia Sensing XCHALLENGE, a competition of companies that are developing software and hardware technologies to improve various aspects of health, were announced. One of them is Elfi-Tech, an Israeli firm that’s been working on a tiny sensor that can detect blood flow in the skin, the pulse and velocity of blood under the skin, coagulation status, and the extent of vascular aging.
The mDLS sensor uses dynamic light scattering for detection, has no moving components, and can be applied almost anywhere on the body. Since Elfi-Tech is focusing on optimizing the sensor itself, it hopes to be able to integrate it into a variety of consumer gadgets from third-party companies like watches, glasses, or stick-on devices.
From the mDLS sensor info page:
The mDLS sensor is easily deployed, simple to operate and robust. Its raw signals translate into novel indices of cardiovascular risks: endothelial function, global coagulation status of the blood, a measurement of Red Blood Cells (RBCs) aggregation rate, and fibrinogen concentration in blood.
In addition, by intensively analyzing the high-resolution blood pulse wave, the sensor can continuously and non-invasively measure a set of physiological parameters such as respiratory rate, systolic blood pressure trends, cardiac contractility, cardiac valve dysfunction and Traube-Hering-Mayer oscillations.
Utilizing this information, the platform can detect health perturbations related to Cardiac, Vascular, Respiratory and Neurological pathologies.
