Abstract
A sensor device is disclosed comprising at least one deformable substrate, at least one transducer element formed in or on a surface area of a first side of the deformable substrate, at least one other transducer element formed in or on a surface area of a second side of the deformable substrate, and electrical conductors formed on and/or in the substrate for electrically connecting between and to the transducer elements.
Claims20
A sensor device, comprising:
- at least one deformable substrate;
- at least one transducer element formed in or on a surface area of a first side of said at least one deformable substrate;
- at least one other transducer element formed in or on a surface area of a second side of said at least one deformable substrate;
- and
- electrical conductors formed on and/or in said at least one deformable substrate for electrically connecting between and to said at least one transducer element,
- wherein the at least one deformable substrate is made from two or more electrically conducting layers attached to an electrically non-conducting film, said two or more electrically conducting layers configured to form the at least one transducer elements and the electrical conductors,
- and wherein the two or more electrically conducting layers comprising a first layer made of a piezoresistive material or compound attached to the electrically non-conducting film, and a second layer made of a material or compound having good electrical conduction properties applied over said first layer on regions of the electrically non-conducting film wherein the first layer been removed or not applied.

A sensor device comprising:
- at least one deformable substrate made from an electrically non-conducting film;
- two or more electrically conducting layers attached to said electrically non-conducting film, said two or more electrically conducting layers having:
- (i) at least one piezoresistive layer selectively attached to said electrically non-conducting film to form at least one transducer element;
- and (ii) at least one conduction layer selectively attached on top of said electrically non-conducting film and to said at least one piezoresistive layer to form electrical conductors electrically connecting between and to said at least one transducer element;
- and
- protective layers applied over the two or more electrically conducting layers formed on top and bottom sides of the electrically non-conducting film to form at least one top protective layer selectively applied over regions of the two or more electrically conducting layers wherein at least one of the transducing elements is thereby formed on the top side of the electrically non-conducting film, and at least one bottom protective layer applied over the two or more electrically conducting layers formed on the bottom side of the film, at least one of said bottom protective layer is made from a material configured to be attached to a plastic object by welding, gluing, extrusion, or overmolding.
