What makes PIEMACS different from traditional vibration sensors?

PIEMACS uses a patented Zero-Mass, Strain-Based MEMS technology that eliminates proof mass entirely. This means no mechanical resonance, no measurement noise, and reliable performance in the harshest industrial environments — from cleanrooms to railway infrastructure.

How early can PIEMACS detect machine failure?

PIEMACS can detect structural fatigue and anomalies up to 6 months before a failure occurs, enabling maintenance teams to act proactively and avoid costly unplanned downtime.

Which industries can use PIEMACS?

PIEMACS is designed for demanding industrial sectors including energy (wind turbines, motors), rail transport, semiconductor cleanrooms, and robotics — any environment with critical rotating or vibrating machinery.

Is PIEMACS easy to install?

Yes. PIEMACS sensors are designed for fast, tool-free installation with minimal disruption to operations. The system is WiFi-enabled and connects directly to the cloud-based AI platform.

Is PIEMACS a funded company?

Yes. PIEMACS is an EPFL spin-off with over 3M CHF in funding and grants, 2 active patents, and participation in 3 European research projects.

More About Us

The problem

Why most predictive maintenance still fails.

Today's systems chase symptoms — not causes. By the time a vibration sensor triggers an alert, the damage is already advanced.

Failure starts inside

Structural degradation begins at the micro-level — inside the component, invisible to external sensors placed on the housing.

Vibration is a secondary
measurement

Conventional sensors measure a consequence, not the cause. The signal is noisy, attenuated, and arrives too late.

Explore Our Process

Early signals are ignored

Cascade failures build undetected for months. When the alert finally fires, you're already in emergency maintenance mode.

AI alone is not enough

Feed a predictive model with the wrong signal and you get wrong predictions. Garbage in, false alerts out.

The solution

One system. Hardware and AI,
end to end.
