Wearable Medical Devices

Wearable medical devices are transforming how physiological data is captured outside traditional clinical environments.

Continuous monitoring enables earlier disease detection, improved patient management, and the development of AI-driven diagnostics.

Designing medical-grade wearables, however, is not merely a repackaging of consumer electronics.

The gap between collecting signals and producing solid clinical evidence is real — and that’s where most wearable programs get stuck.

Clinical-grade devices must demonstrate signal integrity, algorithm transparency, and reproducible validation.

Heart rate, ECG, SpO₂, motion, temperature, and other biosignals can produce clinically meaningful insights when combined over time — but only when the underlying device meets a higher bar.

We help you build these foundations from the start.

From wearable signals to clinical defensibility

One-stop access to multi-disciplinary expertise.

We help you design wearable devices that turn physiological signals into clinically meaningful data.

We help you select, integrate, and optimize biosensors for validated signal quality in a body-worn form factor — accounting for motion artifacts, skin contact variability, and environmental noise.

We design power architectures that maximize operating time while minimizing device size and weight — critical for patient compliance and longitudinal data collection.

We design reliable BLE, NFC, or cellular communication systems that meet medical device cybersecurity requirements.

Compact, ergonomic enclosures with biocompatible materials, ingress protection, and thermal management for extended wear while using certified-for-use parts.

Documented, reproducible on-device signal processing designed for regulatory defensibility.

The full data pathway from device firmware to mobile app to cloud — with data integrity, privacy, and usability built in.

Result-based business model

Cash efficiency is a “do or die” proposition for any early stage company, and hourly-priced projects can quickly lead to cost and time overruns.

Our milestone-based pricing is based on results, giving you the predictability you need to plan your budget with confidence.

And with direct access to our project management system, you have real-time visibility into our progress so you always know where you are.

You pay for: Milestones completed

You don’t pay for: Our time

design for success

From napkin sketch to commercially-viable product, we take a holistic approach to product development, addressing all the required aspects for your device to be successful:

Technical
Ensuring the device can perform as required to deliver the intended clinical results

Usability
Ensuring the device can be operated in the intended clinical setting

Standards
Ensuring the design and development process is documented in compliance with ISO 13485:2016 and that the design meets the requirements imposed by relevant regulatory standards

Manufacturability
Ensuring manufacturing is feasible within your business case assumptions and identifying qualified suppliers and manufacturing partners

Financial
Optimizing device cost of goods sold (COGS)
