The evidence behind the stack.

Sondera is built on peer-reviewed research, and every research output maps onto the same four layers as the technology: Sensing, Edge / Embedded, Intelligence, Automation. No claim on this site reaches further than the work behind it.

Open directions

The research agenda, by layer.

Sensing

THz response of composite structures across materials and damage modes; extension of the measurement architecture to guided waves.

Edge / Embedded

Real-time acquisition architectures, synchronized multi-sensor measurement, and embedded inference for inspection instruments.

Intelligence

Physics-informed defect detection, sim-to-real transfer, uncertainty quantification, and instrument-conditioned synthetic data.

Automation

Adaptive scanning policies, confidence-driven reinspection, and the control architecture for closed-loop NDE.
