The video shows a familiar scene to anyone who has ever set up a complex measurement system: a room covered with cables, sensors, and recording devices, each capturing different signals, all linked by a single synchronization wire.
This visual immediately conveys the challenge of large-scale, multimodal data acquisition: while collecting multiple physiological or mechanical signals is straightforward in isolation, maintaining synchronized, reliable, and scalable acquisition quickly becomes a bottleneck.

From that very challenge grew the motivation for the PhysioEdge system.
At Cosys-Lab (University of Antwerp), we developed a wireless synchronized multimodal physiological acquisition device to remove the hassle of complex wiring and manual synchronization while preserving high-quality, time-aligned data.

This demonstrator shows how we achieve that through intelligent system integration and hardware-software co-design, using commercial off-the-shelf (COTS) components and a custom-designed integration PCB.

Developing this device required bridging the worlds of electronics, embedded systems, and signal processing. Domains where Cosys-Lab has deep expertise.
The demonstrator provides an end-to-end view of this co-design process, illustrating how thoughtful engineering transforms accessible components into a reliable, synchronized, and scalable system.
