How ALL WAVES TouchTM technology works

1.Sensors bonded to the structure generate vibration waves.

2.These waves propagate through the structure and are reflected by any object in contact.

3.Our patented algorithm analyses the reflected waves and determines the coordinates of contact points and the contact pressure applied to them.

Versatilité

Make any structure tactile

ALL WAVES TouchTM technology is the only technology that makes tactile large, or curved structures or structures with a complex geometry. It is based on the propagation of “guided” ultrasonic vibration waves in the structure. These waves have the particularity of being able to propagate over several meters without attenuation.

Sensibilité

Increased sensitivity to any type of contact

Once instrumented, the structure becomes sensitive to any type of contact, whether a finger (with or without glove), a sharp object (pencil, stylus), a cup, etc. An object in contact the structure modifies the behaviour of the vibratory waves that propagate there. The localization of the contacts is instantaneous since the vibration waves travel in the structure at a speed of several kilometers per second.

Facilité

Easy integration and robustness

Our tactile technology is not affected by the presence of liquid and solid contaminants or scratches on the surface. The sensors are installed on the edge of the structure, which allows maximum transparency to be maintained while ensuring minimum space requirements. The sensors can be bonded directly to the structure or integrated inside it. No need for a controlled environment, this operation can be done in the factory.

Économique

Save costs

ALL WAVES TouchTM technology is very economical. A small number of sensors allows any structure to be tactile.
