Accurate Weight and 3D Force Sensing for Car Seats
At 100km/h, Algorithms Guess.
Physics Knows.
Movetrics Vector S3:
The first Structural Biometric Interface for the automotive industry. Achieving Euro NCAP 2026 precision without the drift of pressure mats or the privacy risks of cameras.
Gravity does not lie.
The Era of “Good Enough” is Over.
For twenty years, the automotive industry has relied on a compromise. To detect passengers, we buried sensors inside seat cushions—fighting a losing battle against foam aging, temperature hysteresis, and the laws of thermodynamics.
Then came the cameras. They promised intelligence but delivered privacy nightmares, GDPR roadblocks, and failure in the dark.
And now, Euro NCAP 2026 demands the impossible:
- You must distinguish a 30kg child from a 30kg box.
- You must detect “Out-of-Position” (feet on dashboard) instantly.
- You must do it without invasive surveillance.
The old tools are broken. You cannot solve a physics problem with better software. You must solve it with better mechanical engineering.
The Challenge: Euro NCAP 2026
New regulations demand accurate occupant classification. Current solutions fall short.
Stature Classification
4 points for classifying 5th, 50th, and 95th percentile occupants
Child Presence Detection
5 points for detecting children, even under blankets
Out-of-Position Detection
2 points for detecting dangerous occupant positions
Crash Occupancy
5 points for accurate eCall occupant data.
We Moved the Measurement.
We Fixed the Problem.
Movetrics Vector Platform is not a sensor pad. It is a structural evolution of the seat rail.
By integrating a patented multi-axis load cell array directly into the chassis interface, we bypass the seat cushion entirely.
We do not measure surface pressure. We measure Reaction Force.
The “Structural Truth” Architecture:
- Kinematic Decoupling: Our patented spherical-bearing interface isolates vertical load Fz from chassis torque. Even if the car floor flexes during cornering, the measurement remains absolute.
- Zero-Drift Steel: Unlike capacitive sensors or foam, steel does not age. It does not harden in winter or soften in summer. It requires zero recalibration over the vehicle’s lifespan.
- 20mm Integration: A low-profile, drop-in architecture compatible with standard Faurecia, Adient, and Lear seat track profiles.

Questions and Answers
Why not just use cameras for Out-of-Position detection?
Cameras require line-of-sight. If a passenger is sleeping under a blanket, reading a large newspaper, or sitting in darkness, the camera is blind. Furthermore, cameras face massive GDPR scrutiny for recording biometrics in the cabin. Tensoa measures force—which cannot be hidden and is privacy-neutral.
Do your load cells drift over time?
We use a patented kinematic decoupling interface that isolates the load cells from chassis torque and thermal expansion. Unlike foam-based sensors that degrade and harden over years, structural steel maintains calibration for the vehicle’s lifespan.
How does this integrate with current seat designs?
Vector-S3 is a drop-in structural component. It sits between the seat rail and the chassis, adding only ~20mm of Z-height. It utilizes standard mounting bolts and requires no redesign of the seat foam, trim, or heating elements.
What is the data latency?
<10ms. Because we measure direct reaction force, there is no complex image processing lag or AI inference time. This speed is critical for pre-crash restraint deployment (e.g., pretensioners).
