Flexible packaging for tyre integrated shear force sensor

Wireless Si 3D force sensor made by MEMS technology was integrated and tested on the sidewall of a tyre using flexible rubber repair patch (patent pending) in order to monitor the deformation of the rotating tyre in automotive applications. Finite element simulation was used to determine the optimal positioning of the sensor structure. Power supply and wireless communication is based on inductive coupling. Static characterization on a measurement pad and preliminary real life-testing has been carried out.
