A patch that gives structures a voice.

Ultrasonic guided waves, on-board processing, optical fibres and AI: how the patented device works and why it is built for the field.

01 · THE PROBLEM

An inspection captures a single moment. Sense&Learn follows the structure throughout its service life.

A

Ageing critical assets

Wind turbine blades, bridges, hydrogen tanks and aerostructures increasingly remain in service beyond their design life and under more severe loads than planned.

B

Hidden damage between inspections

In composites, impact damage and the resulting delaminations are often not visible on the surface (BVID). Periodic inspections cannot track their growth.

C

Costs that never show up in the books

Unplanned downtime, emergency repairs and structures oversized by conservative safety factors.

02 · THE DEVICE

Apply it, connect it, listen.

At the heart of the patent is a flexible, removable printed circuit with seats for interchangeable piezoelectric transducers, connected to a microcontroller module that processes the signals autonomously.

  1. 01Flexible-circuit patchConforms to flat and curved surfaces; the sensor arrangement is designed for the component.
  2. 02Removable PZT transducersFitted into dedicated seats: the network can be reconfigured or repaired without reinstalling the patch.
  3. 03Processing moduleGenerates the excitation, acquires and processes the signals on board, with no external instrumentation.
  4. 04Smartphone controlStart measurements and view the damage map over Bluetooth, directly in the field.

THE DEVICE IN 30 SECONDS From the panel to the damage map. The patch is applied to the structure, connected to the acquisition module and operated from a smartphone via Bluetooth. Being flexible, it also conforms to curved surfaces.
03 · HOW IT WORKS

From signal to decision in four steps.

The device works in active mode, interrogating the structure on demand, or in passive mode, listening to record events such as impacts.

  1. 01 — Excitation

    Guided waves

    One transducer emits a burst of ultrasonic waves that travels through the structure; the others receive the signal in a pitch-catch configuration.

  2. 02 — Acquisition

    On-board processing

    The microcontroller acquires and pre-processes the signal of every actuator–receiver path, directly on the device.

  3. 03 — Diagnosis

    Detection and localisation

    Damage indices, numerical models and AI/ML algorithms estimate the presence, position and extent of damage.

  4. 04 — Decision

    Condition-based maintenance

    The damage map reaches a smartphone or dashboard: intervene where needed, when needed.

MULTIMODAL PLATFORM

More signals, fewer false alarms.

We handle the whole chain: sensor selection and integration, acquisition electronics, data management and visualisation of results. Combining several quantities makes diagnosis more robust under real operating conditions.

Coin-sized piezoelectric transducers excite and receive guided waves that propagate through the material. They detect cracks, delaminations and internal damage, even in complex composite or metallic structures.

04 · WHY SENSE&LEARN

Built for the field, not just the lab.

Sensor performance matters, but so does how easily it can be installed, used and replicated across a fleet of assets.

ON-BOARD

On-board intelligence

Processing on the device reduces the data to transfer, complexity and operating costs: no external acquisition system to bring on site.

INTELLECTUAL PROPERTY
EP 4540588 European patent granted. Upcoming applications will address PZT and optical-fibre integration and AI/ML diagnostics.
Flexible Sense&Learn patch applied to a curved surface

Curved surfaces too

The flexible patch conforms to curved surfaces and stiffened panels.

Minimal wiring

Fast installation, reduced downtime, no cable bundles running to an acquisition rack.

Ready for technicians

On-site tests and immediate results on a smartphone, even in hard-to-reach areas.

From component to fleet

Same platform, repeatable installations, data comparable across assets.

Traceable decisions

Objective reports and indicators for quality, HSE, audits and compliance: every intervention is justified by measured data.

Physics-guided AI

Numerical models and digital twins work alongside machine learning: not just a classification, but an interpretable estimate of the structure’s condition and how it is evolving.

05 · IN THE FIELD

Structural health in your pocket.

The technician starts a measurement over Bluetooth and sees the damage map directly on the phone. Data can feed a dashboard that keeps the asset’s history.

ACTIVE MODEOn-demand interrogation, at set intervals or before every mission.
PASSIVE MODEContinuous listening to record and locate impacts.
