A wearable medical device development company built around power, skin contact and motion.
A wearable is a different design problem than a bench-top or bedside device — power has to last days on a coin cell, the sensor has to work against skin instead of in a controlled setting, and motion from the wearer's own body is the main source of noise. Rivix scopes hardware, firmware, cloud and app together for that specific set of constraints, with a named senior engineer accountable end-to-end.

Power is the design constraint, not an afterthought
Sampling rate, radio duty cycle and display (if any) get sized against a target battery life measured in days or weeks on a coin cell or small rechargeable cell — decided before component selection, not tuned after the board is laid out.
Motion artifact is the main noise source
An accelerometer alongside the physiological sensor flags motion-corrupted samples; adaptive filtering and firmware-level confidence scoring reject or flag low-confidence readings instead of reporting them as clean data.
Skin contact shapes both hardware and enclosure
Electrode or optical sensor placement, biocompatible materials, and an enclosure that stays comfortable for extended wear all get decided together with the sensing approach — not treated as separate industrial-design and electrical problems.
Regulatory rigor scoped to the actual claim
A wearable making a diagnostic or treatment claim is held to full IEC 62304 / ISO 14971 rigor; a wellness-focused wearable without a medical claim has more latitude, but the reliability and data-handling practices are usually worth carrying over regardless of classification.

What people ask before scoping a wearable medical device.
What makes wearable hardware different from a bench-top or bedside medical device?
Power budget, skin contact and motion artifact rejection dominate the design. A wearable typically runs on a coin cell or small rechargeable battery for days to weeks, has to stay comfortable against skin for extended wear, and has to distinguish a real physiological signal from noise caused by the wearer's own movement.
How do you handle motion artifact in wearable sensing?
Usually a combination of sensor fusion (an accelerometer alongside the physiological sensor to flag motion-corrupted samples), adaptive filtering, and firmware that either rejects or flags low-confidence readings rather than reporting them as clean data.
Do wearable medical devices need the same regulatory rigor as other medical devices?
It depends on the intended use and claims — a wearable making a diagnostic or treatment claim is held to the same IEC 62304 / ISO 14971 rigor as any other medical device; a wellness-focused wearable without a medical claim has more latitude.
