Steve Majerus, Ph.D.
Dr. Majerus completed his PhD in electrical engineering in 2014 at Case Western Reserve University focusing on low-power electronics for health monitoring. In this work, he developed the first example of a real-time, wireless, bladder pressure sensor suitable for cystoscopic implantation directly into the bladder wall. Dr. Majerus has expertise in custom, application-specific integrated circuits (ASICs) for demanding applications in biomedical, aerospace, and high temperature applications. Additionally, Dr. Majerus has extensive experience in multiresolution signal processing, custom radio architectures, wireless battery charging, and biocompatible microsystem encapsulation.
Dr. Majerus is continuing his research career as an APT Center Investigator focusing using innovative technologies to enable and enhance bio-sensors for medical health monitoring. Dr. Majerus received a VA Career Development Award, co-edited Implantable Biomedical Microsystems: Design Principles and Applications, authored numerous peer-reviewed conference and journal manuscripts, and has several pending patents.
Dr. Majerus has several active projects:
1. Noninvasive vascular access monitoring using phonoangiograms
2. Flexible pulsation sensors for measuring vascular graft patency
3. Closed-loop bladder neuromodulation using wireless pressure sensors
4. Broadband intravascular ultrasound using catheter-mounted CMOS frontends

Dr. Majerus' research is multi-disciplinary and focuses on a core competency in low-power, miniaturized electronics combined with microsystem assembly, polymeric packaging, and flexible circuits and sensors. These device examples were each designed to address unmet clinical needs for Veterans with spinal cord injury, end stage renal disease, or peripheral vascular disease.
