1. A device comprising:

  • a deformable shell defining an inner space and comprising at least one piezoelectric system;

    wherein said at least one piezoelectric system comprisesa flexible piezoelectric membrane capable of generating electric energy under the effect of a deformation to which it is submitted,an electric power source formed on a flexible substrate, andan electronic circuit, wherein the electronic circuit comprisesa processing circuit for generating and storing data according to the electric energy generated by the piezoelectric membrane, and connected to the electric power source for its electric power supply, anda wireless transmitter connected to the processing circuit to transmit the data stored therein and connected to the electric power source for its electric power supply;

    wherein in the device, each of the at least one piezoelectric system is totally arranged on and/or inside of the deformable shell; and

    wherein the piezoelectric membrane, the electric power source and the electronic circuit are stacked on one another, and the electric power source is arranged between the piezoelectric membrane and the electronic circuit.
