Multi-point RF system for near-field coherent sensing (NCS)

New paper demonstrates effectiveness of measuring full blood pressures without an arm cuff

Professor Edwin Kan, along with Xiaonan Hui and Thomas Conroy, both Ph.D. students in Kan’s research group, are the authors of the paper titled “Multi-Point Near-Field RF Sensing of Blood Pressures and Heartbeat Dynamics.” “Blood pressures measured by an arm or wrist will give you ‘brachial pressures’ instead of the central pressure,” Kan explained. “Brachial pressures can be similar if the cuff is maintained at the height of the heart, but it is an indirect measurement together with the arm condition.” Cuff-based measurements provide an estimate of an average blood pressure over a number of...

Student team eyes next steps for ventilator designed in a bedroom lab

Landon Ivy started his Ph.D. work with Professor Amit Lal’s SonicMEMS Lab, developing new processes for micro electrostatic linear actuators which will eventually drive the locomotion of a microbot. He had cultivated an affinity for working on hardware during his undergraduate studies, and when he got to Cornell he spent as much time as he could in the Cornell NanoScale Facility (CNF). Then the pandemic forced Ivy along with all of his SonicMEMS Lab colleagues off campus. “A few days later, Dr. Lal got the word that there would be a ventilator shortage, so he encouraged the group to brainstorm...
