Abstract

A flexible film of crystalline or semi-crystalline material comprising a first region surrounded by a first amorphized wall.

First claim

The invention claimed is:

1. A flexible film of a material in a crystalline or semicrystalline form, said film comprising first and second opposite faces and comprising, between the first and second faces, a first region of said material in the crystalline or semicrystalline form surrounded with a first wall of said material in an amorphized form.

2. The flexible film of claim 1 , wherein the first amorphized crosses the entire film from the first face to the second face.

3. The flexible film of claim 1 , wherein the material is polyethylene naphthalate or polyethylene terephthalate.

4. A sensor comprising:
the flexible film of claim 1 ; and
at least one first electric component formed on the first region and resting on the first face.

5. The sensor of claim 4 , wherein the first electric component is a first heat-sensitive resistor.

6. The sensor of claim 5 , wherein the first heat-sensitive resistor is made of a resistive paste.

7. The sensor of claim 5 , wherein the flexible film comprises a first cavity different from the first region surrounded with the first wall, the sensor further comprising a second heat-sensitive resistor formed in the first cavity.

8. The sensor of claim 7 , comprising third and fourth heat-sensitive resistors assembled as a Wheatstone bridge with the first and second heat-sensitive resistors.

9. The sensor of claim 8 , wherein the flexible film comprises a second region surrounded with a second amorphized wall, the third heat-sensitive resistor being formed on the second region.

10. The sensor of claim 9 , wherein the flexible film, comprises a second cavity different from the first region surrounded with the first wall and from the second region surrounded with the second wall, the fourth heat-sensitive resistor being formed in the second cavity.
