Researchers Create Tiny 3D Printed Telemetric Sensors Designed For Cardiac Research

Advanced testing of medical treatments often involves experimentation on small laboratory animals like genetically modified mice. The work itself helps researchers develop medication and cures for humans illnesses, and that’s created a need for innovative telemetry systems to enable remote, real-time monitoring … of various biological processes. Perhaps the most critical applications of these technologies are related to cardiac monitoring.

Researchers have focused on creating wireless, implantable systems with integrated blood pressure sensors and fully implantable cardiovascular pressure monitors which include a stent. But the design of such systems gets dicey when designers are forced to deal with smaller-sized test subjects as opposed to larger patients like human beings. Large external components – with larger power sources – just won’t fit the bill.

Now work by Kyle G. Fricke at the University of Western Ontario and done under the direction of Dr. Robert Sobot is focusing on the design of a wireless telemetry system architecture, intended to retrieve blood pressure and volume data that, due to its design and prototyping with 3D printing processes, checks in at a svelte 2.475 cm3 and weights just over 4 grams. … (Read more)
