Abstract
An adhesive skin patch and a method that enables provision of an adhesive skin patch which is very thin, conforms easily to deformations of the skin and can still be manufactured in a sequentially progressing industrial process that can be automated for commercial production. The adhesive skin patch includes conductive parts that provide contact to the skin and access for external electrical contacts.
Claims20
An adhesive skin patch including a first layer of polysiloxane, a first conductor and an adhesive layer;
- wherein
- the first conductor comprises a conductor region and a sensing region that is in electrical connection with the conductor region;
- the first layer of polysiloxane includes an opening to at least part of the conductor region of the first conductor or to a further conductive layer electrically connected to the conductor region of the first conductor by one or more vias;
- the adhesive layer includes an opening to at least part of the sensing region of the first conductor.
A method for creating a layer structure for adhesive skin patches, the method including:
- depositing on a layer of liquid-soluble polymer a first layer of polysiloxane that is patterned to include an opening and cured to function as an elastic solid;
- depositing on the first layer of polysiloxane a first conductor that includes a conductor region and a sensing region that is in electrical connection with the conductor region or depositing on the first layer of polysiloxane a second conductor, at least one intermediate layer of polysiloxane and a first conductor that includes a conductor region and a sensing region, wherein the conductor region of the first conductor or the second conductor is aligned to at least partly coincide with the opening in the first layer of polysiloxane;
- depositing on the first conductor a layer of skin-adhesive patterned to include an opening that coincides with the sensing region of the first conductor.
