A tire, comprising a module and a receptacle connected to an inner surface of the tire. Therein, the receptacle comprises wall(s), which wall(s) limit(s) openings comprising at least a first opening and a second opening. Therein, part of the module extends through at least the second opening such that the wall(s) of the receptacle laterally surround(s) only a first part of the module such that at least a second part of the module is arranged outside the receptacle.

A deformable sensor arrangement includes a deformable sensor attachable to a curved surface. The deformable sensor includes an elastic layer having a Young's modulus at least 0.01 MPa and a first yield strain at least 10%. A first stretchable electrode attaches to the elastic layer, and a stretchable electrically conductive wiring. The first stretchable electrode and the stretchable electrically conductive wiring stretch at least 5% without breaking. An electronic arrangement electrically couples to the first stretchable electrode via the stretchable electrically conductive wiring and obtains a first signal from the first stretchable electrode. An analyzer determines a calibrated value based on the obtained first signal and assembly compensation coefficients, which are based on material compensation coefficients, and a measured signal of the deformable sensor in its installing position. A system and method are for installing the arrangement. A method and computer program determine a value of interest.

Deformable sensor

A tire comprising a tread block made of tread material, a tread, of which a part is formed by the tread block, and an insert comprising a primary capacitive component and a primary inductive component. The insert extends in a longitudinal direction from a bottom of the insert to a top of the insert. The insert has a first cross section at a first longitudinal position and a second cross section at a second longitudinal position, wherein the first longitudinal position is located closer to the tread of the tire than the second longitudinal position, and the second cross section is greater than the first cross section. At least a part of the top of the insert does not form an interface with the tread material. A method for applying an insert into a tire. An insert is inserted into a blind hole of the tire such that the bottom of the insert is inserted deeper in the blind hole than the top of the insert.
