On January 14, 2025, President Biden awarded Dr. Majerus the Presidential Early Career Award for Scientists and Engineers (PECASE), which is the highest honor bestowed by the U.S. government on outstanding scientists and engineers early in their careers.
You can also read the full press release.
Four Case Western Reserve University faculty received PECASE awards this round, and CWRU published a nice summary article as well.
Jeremiah Ukwela recently defended his MS thesis “Finite Element Informed Optimization of an Implantable Flexible Blood Pressure Sensor” at Case Western Reserve University School of Engineering.
Jerry’s work led to an order of magnitude increase in sensor sensitivity and paved the way to developing a sensor for parasympathetic activation.
Jerry’s excellent work was accompanied by an equally excellent public presentation at CWRU.
Congratulations once again on finishing your thesis!
We have two papers at the upcoming BIOCAS 2023 conference in Toronto, Canada. The 4-page papers will be available on IEEEXplore after the conference. Here is a preview:
Analog Interface Amplifiers for Sub-mm Broadband Polymer Intravascular Ultrasonic Imaging
Authors: Ruiyan Wang, Isaias TreviƱo, Aaron Fleischman, Steve JA Majerus
Conformal Ultrasound Transducer Array for Image-Guided Neuromodulation
Authors: Vida Pashaei, Junjun Huan, Haoyang Chen, Mohamed S.E.A. Osman, Sri-Rajasekhar Kothapalli, Steve JA Majerus, Soumyajit Mandal
Check out this article describing a double helix antenna for implantable devices. The double helix structure is unique as it is printed “flat” but captures magnetic flux after wrapping. This allows much more flexibility for surgical deployment or other form factors compared to traditional wound wire inductors.
The paper mainly focuses on modeling the antenna, but we also demonstrated a proof-of-concept using RFID to monitor blood flow. This could be used, for example, as a post-surgery monitoring system.
A Flexible Double Helix Inductive Antenna for RFID Vascular Flow Sensing
IEEE Sensors Journal

Check out our latest article describing a bowel pressure and content sensor tested in human-scale animals:
This article describes our first-in-human demonstration of the UroMonitor sensor.
Unlike traditional diagnostic testing which uses catheters in a clinic, this device enables monitoring of symptoms as the patient lives their life. We hope the future of urodynamics testing is catheter free!

Congrats to the team for a Best Paper award from the IEEE SPMB conference!!
This approach may cut the number of catheters needed for urodynamics in half. Half the waste, less patient discomfort, and fewer recording artifacts. We will be expanding on this topic in an upcoming book chapter in 2023.
Our papers focusing on signal processing with bladder pressure data will be presented at IEEE SPMB 2022. The papers involve machine learning to detect multiple bladder events in real time, and estimation of bladder pressure using only a single catheter (versus today’s standard that uses two catheters). Congratulations to all authors!
We were honored to receive the Best Paper Award at IEEE Sensors 2022 in Dallas, Texas. Congratulations everyone!
Special thanks to NIH SPARC for sponsoring this research and the IEEE Sensors Program Committe for the recognition.
We look forward to presenting new work at IEEE Sensors 2023 in Vienna, Austria.
