Presentation at the 2026 IEEE Midwest Circuits & Systems Conference (MWSCAS)

Dr. Majerus presented A 4-MHz Miniaturized Inductive Receive Chain for Closed-Loop Neuromodulation with Bladder Pressure Feedback on behalf of Leo Yang.

This work leverages the COSMIIC open-source neuromodulation system. We built a custom radio link that enables our previous wireless pressure sensor to send data directly to the implant, no external antennas needed! Software on COSMIIC interprets data in real time to decide when to stimulate the bladder, in an important step to building a neuroprosthesis for urinary continence.

Contact the COSMIIC team if you are interested in the technology!

Angel defends his MS Thesis: Implantable Multimodal Hemodynamic Sensor Array

Angel’s research investigated how multiple implantable sensors (combining vascular distension, acoustic, and optical modes) can robustly sense hemodynamics in real time. Because the sensors use different modalities, time-based feature cross-correlation can potentially enable new insights into physiology.

Congratulations to Angel, and we wish him the best of luck now that he has graduated!

Congratulations to Ben for defending his MS thesis!

Ben recently defended his MS thesis “Near-Field Data Transmission using Power- and Volume-Efficient Split Canted-Cosine-Theta Coils.”

This research focused on developing omnidirectional antennas useful for short-range communication to medical implants. Interestingly, these coils can be scaled up (or down) to detect the primary direction of magnetic fields in industrial applications, cytometry, or even particle physics.

The image shown is of a previous version. Ben’s work is currently embargoed while patents are filed.

Eli successfully defends his thesis!

Congratulations to Eli Hinson for passing his MS thesis defense!

Eli’s thesis is titled “Automated Point-of-Care Bladder Pressure and Volume Measurement Device for Urodynamic Monitoring.”

The motivation behind this work is to build a simpler tool to detect hostile bladder or other urologic conditions which can happen after spinal cord injury (SCI). Regular monitoring of bladder pressure after SCI is an often-overlooked preventative measure. The hope is to one day make this technology available for disposable, at-home use.

Dr. Majerus is awarded the prestigious PECASE recognition

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.

Congratulations Jerry!

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!

New Article: A Flexible Double Helix Inductive Antenna for RFID Vascular Flow Sensing

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.
