Independent hardware consulting for the teams building the next generation of bio-sensing wearables. Ultra-low-power analog front-ends, BLE SoC strategy, and IEC 60601 compliance — with a track record of boards that ship without redesign.
ScanVibe Consulting is the independent engineering practice of Dr. Cezar Morun — an R&D engineer who has spent two decades turning bio-sensing concepts into shipping wearable medical products.
The work sits where analog, digital, RF, power, and regulatory constraints collide: ECG, PPG, EMG, EMS, and related modalities, engineered to clinical-grade reliability inside wearable form factors. Clients engage ScanVibe when they need a senior hardware architect who has lived through the full cycle — architecture, schematics, HDI PCB, firmware, EMC/EMI, and IEC 60601 certification — and can deliver judgment calls that protect the timeline as much as the engineering.
The track record is specific: boards that have passed EMC/EMI and IEC 60601 testing on the first iteration, battery-life gains measured in multiples rather than percentages, and platform roadmaps grounded in a realistic view of the silicon landscape.
ECG, PPG, EMG, EMS, EEG, GSR, core body temperature, blood pressure, respiration, and acoustic. Analog front-end design optimized for SNR at ultra-low power.
Mixed-signal system design, power-tree strategy, signal-integrity planning, and high-density HDI PCB architecture for medical-grade wearables.
Platform selection and upgrade paths across Nordic nRF5340 / nRF54L series, Ambiq Apollo, and leading module vendors — including BLE 6.0 and Channel Sounding readiness.
Full schematic capture and HDI PCB layout for multi-layer medical wearables — from concept to complete manufacturing documentation, with a high respect for DFM, DFT and BOM optimization for cost and supply-chain resilience.
System-level power budgeting, power-tree redesign, and hardware duty-cycle optimization — with battery-life gains routinely measured in multiples rather than percentages.
Zephyr RTOS, modern BLE stacks, and embedded C — with firmware optimization passes that routinely double usable battery life without touching the cell.
Design reviews, platform assessments, and silicon-landscape studies that help founders and CTOs make multi-year decisions with confidence.
IEC 60601-1, 60601-1-2 (EMC), 60601-1-11 (home healthcare), 60601-2-10 (TENS/EMS), 60601-2-47 (ambulatory ECG), ISO 10993 biocompatibility, and risk-management workflows.
Prototype build support, DFM and DFT review, test fixture and protocol definition, technical documentation for CM handoff, and contract manufacturer selection — from first EVT board to volume production.
A 30-minute conversation to understand the problem, stakeholders, timeline, and constraints. No slide decks, no salespeople.
A short written proposal with deliverables, milestones, pricing, and NDA. Usually turned around within a week of the initial call.
Senior-only work. Direct communication with the engineering team, regular written updates, and deliverables that match the proposal.
Structured handoff to your team, with optional follow-on support — design reviews, EMC-test preparation, or platform evolution.
