In early 2016, University of Waterloo, Canada researchers announced the creation of a portable, noninvasive device designed to provide real-time monitoring of blood flow throughout the entire body. The touchless device employs a coded hemodynamic imaging approach to measuring blood flow at several arterial points.

Traditional blood-flow measurement approaches rely on blood-pulse readings at single points in the body. Whole-body imaging, coupled with continuous data collection, offers a much better picture of what is occurring throughout the body. The new photoplethysmographic imaging (PPGI) approach does not involve skin contact, as sensors use ambient and active light fluctuations as a way of measuring changes in local blood volume. The PPGI system has several potential uses, and may be particularly suited to monitoring neonatal intensive care infants and patients with severe burns and extremely contagious diseases.
