Ultra-thin & conformal
At 0.3 mm the film conforms to curved test surfaces without changing the contact geometry being measured.

Why Flexible
Why blades need pressure sensing that can be bonded on
Conventional pressure taps are bulky and sparse, so they cannot reconstruct a continuous pressure field. A thin sensing film conforms to curved surfaces and turns point measurements into surface mapping.
Array-based mapping
Multi-point arrays on a single film deliver a pressure distribution rather than a handful of isolated readings.
Built for outdoor duty
Encapsulation designed for temperature swings, humidity, salt spray and long-term vibration.
Full-stack delivery
Sensors, acquisition, transmission and platform delivered together — usable data, not just components.
Products
Four components, one measurement chain
Film, collectors and software are specified together — the sheet count follows the surface size.
PD-FS
4096-point sensing film
A piezoresistive film with a 64 × 64 sensing matrix on a 490 × 520 mm sheet. Each sheet is an independent measuring unit; multiple sheets tile to cover larger surfaces while remaining individually replaceable.
- 0.3 mm, conforms to curved surfaces
- 4096 points per sheet, tiled to any area
- Individual sheets replaceable without rebuilding the panel
PXS064mini
Compact 4096-point collector
USB collector for one sensing sheet — 90 × 40 mm and under 100 g, so it sits beside the fixture rather than on it. Grouped through a docking hub.
- 90 × 40 mm, under 100 g
- One 4096-point sheet per unit
- USB to docking hub
PXS128
Large-format collector
180 × 180 mm unit for builds where five larger collectors replace ten compact ones — fewer devices and less cabling at the hub.
- 180 × 180 mm, under 200 g
- One 4096-point sheet per unit
- Half the collector count of Config B
PD-SOFT
One session, all sheets
The bundled application merges every collector into a single pressure map, with recording, playback and raw data export.
- All sheets in one window
- Per-sheet calibration
- CSV export for external analysis
Applications
We go deep in one application, then reuse the capability
Wind turbine blades are our main field. The same sensing stack extends to industrial equipment and structural testing.
Primary application
Blade surface pressure mapping
Sensor arrays bonded at critical blade sections continuously capture surface pressure for load assessment, design validation and condition comparison.
- Design validation: measured distribution vs. simulation
- Load and fatigue assessment: locating pressure concentration
- Condition monitoring: tracking long-term pressure signatures
Industrial equipment & robotics
Grip force control, assembly surface inspection and fixture load analysis — replacing discrete force sensors with full-surface arrays.
- Grip force closed loop
- Assembly pressure uniformity
Structural & rail monitoring
Long-term measurement of contact pressure, wheel-rail forces and load conditions on structural components.
- Long-term contact pressure records
- Anomaly event replay

Config B
20,480 points across a 2.5 m² blade panel
Five long sheets and ten compact collectors merged into one continuous map over 1040 × 2480 mm, then compared against the aerodynamic model.

Config C
Bond-line pressure during spar cap bonding
Adhesive pressure mapped along the bond line before cure, replacing a trial-and-error shim routine.
Industrial
Config A
Press platen uniformity before a curing change
40,960 points across ten sheets measured platen flatness under load, so the process change was decided on data rather than a sample.
FAQ
Frequently asked questions
Conventional sensors are rigidly packaged and measure a single point, usually requiring a tap or mounting port. A flexible film is thin — 0.3 mm in our standard sheet — conforms to curved surfaces and can be patterned into arrays, delivering a pressure distribution instead of a single value.
Aerodynamic loads on a blade appear directly as surface pressure distribution. Measuring it allows you to validate simulation models, assess loads at critical sections, locate concentration zones and support maintenance decisions.
The film is sub-millimetre and conformal, so its influence on the airfoil is minimal. The final encapsulation scheme depends on the blade geometry, operating environment and required monitoring period.
Yes. Sheet size, point count and seam layout follow the measured surface. The standard range is 400–6000 kPa and can be customized; collectors come in two form factors and are grouped through a docking hub, so a build can scale to 10 sheets and 40,960 points.
Yes. We work with customers in Europe and North America and can support export documentation, remote commissioning and on-site installation for larger projects.
