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.

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!

Open PhD Positions

We currently have two open PhD positions in applications relating to implantable neuromodulation systems and intravascular ultrasonic imaging. Both positions would involve opportunities including medical ASIC design, microsystem integration, and sensor interfacing. Interested candidates should email Dr. Majerus.
