Abstract
An electro-mechanical model has been developed for the functioning of a tactile polymer coating with a built-in fiber optic piezoelectroluminescent (PEL) sensor and many villi (vibrisses) on the surface of the coating along the sensor. Local deformation of the coating and the built-in sensor is carried out in the disturbance zones, witch are local areas of the coating (sensor) near the points of cantilever fastening of the tufts at their contacts with the analyzed object. Mechanoluminescent effect occurs on deformed sections of sensor when electric field of section of its piezoelectric layer affects adjacent section of electroluminescent layer. Modeling and analysis of substantially inhomogeneous deformation and electric fields occurring in piezoelectric and electroluminescent layers of the sensor were carried out and characteristic forms of generated informative light signals for different cases of deformation of bending villi in different planes and torsion as a result of contact of villi ends with the surface of the analyzed object were revealed.
