ScanVibe Consulting • Est. 2023

Engineering wearable medical devices that pass on the first try.

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.

Capabilities

Full hardware ownership across the wearable medical device stack.

01 / SENSING

Bio-Sensing Modalities

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.

02 / ARCHITECTURE

Hardware Architecture Design

Mixed-signal system design, power-tree strategy, signal-integrity planning, and high-density HDI PCB architecture for medical-grade wearables.

03 / CONNECTIVITY

BLE SoC Selection / Platform Strategy

Platform selection and upgrade paths across Nordic nRF5340 / nRF54L series, Ambiq Apollo, and leading module vendors — including BLE 6.0 and Channel Sounding readiness.

04 / PCB

Schematics & PCB Design

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.

05 / POWER HW

Ultra-Low Power Hardware Optimization

System-level power budgeting, power-tree redesign, and hardware duty-cycle optimization — with battery-life gains routinely measured in multiples rather than percentages.

06 / POWER FW

Ultra-Low Power Firmware Optimization

Zephyr RTOS, modern BLE stacks, and embedded C — with firmware optimization passes that routinely double usable battery life without touching the cell.

07 / DILIGENCE

Technical Due Diligence

Design reviews, platform assessments, and silicon-landscape studies that help founders and CTOs make multi-year decisions with confidence.

08 / COMPLIANCE

IEC 60601-xx Compliance Guidance

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.

09 / MANUFACTURING

Production Readiness

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.

Selected outcomes

Shipped results, not claims.

BLE · ROADMAP
Platform upgrade assessment for BLE 6.0 early adoption
Delivered a technology-upgrade study guiding migration from a current-generation BLE SoC to a next-generation platform with Channel Sounding — used to drive the client's multi-year product roadmap.
2024 — 2025
POWER · WEARABLE
Battery life more than doubled — cell unchanged
Architectural proposal for a sleep-diagnostics wearable that targeted more than 2× usable battery life without increasing battery capacity, through power-tree and duty-cycle redesign.
2024 — 2025
SOC · STRATEGY
Comparative Nordic SoC landscape study
Seven-family comparative analysis across ~70 parameters, enabling the client to select a successor SoC for a dual-SoC wearable architecture with confidence.
2024
EIT · PEDIATRIC
Low-noise power & comms for a pediatric EIT device
Defined the power architecture and communication subsystem for a pediatric electrical impedance tomography device used to screen and monitor vesicoureteral reflux — meeting stringent noise-injection targets.
2022
LUNG · MONITORING
Multiple wearable lung-monitoring boards, no redesigns
Delivered several generations of high-density, ultra-low-power hardware for a wearable lung-monitoring platform — every board met specification on the first iteration.
2021 — 2023
BP · CUFFLESS
3× SNR & battery-life improvement on a cuffless BP wearable
Architectural redesign of a continuous blood-pressure wearable lifted SNR and battery life by more than 3×. Firmware optimization added a further 50% runtime; the product exceeded all clinical-trial performance thresholds on the first attempt.
2020 — 2023
EMC · IEC 60601
First-pass compliance on a children's wearable
A health-and-wellness wearable for children integrating multiple bio-sensing modalities passed every EMC/EMI and IEC 60601 test on the first iteration — zero redesigns, zero compliance re-tests.
2016 — 2018
IP · INVENTION
Co-inventor on granted US patents across multiple programs
Named co-inventor on granted US patents and applications spanning physiological sensing, EMG biopotential, and oscillometric respiratory monitoring — including US Patent 11,006,843.

How it works

A straightforward engagement.

STEP 01

Discovery call

A 30-minute conversation to understand the problem, stakeholders, timeline, and constraints. No slide decks, no salespeople.

STEP 02

Scoped proposal

A short written proposal with deliverables, milestones, pricing, and NDA. Usually turned around within a week of the initial call.

STEP 03

Focused execution

Senior-only work. Direct communication with the engineering team, regular written updates, and deliverables that match the proposal.

STEP 04

Handoff & support

Structured handoff to your team, with optional follow-on support — design reviews, EMC-test preparation, or platform evolution.
