Abstract
A thin-film electrochemical device includes a monolithic substrate, which includes a cavity enclosed by bottom and side surfaces of the substrate, and a thin-film arranged on a top surface of the substrate and enclosing the cavity. The thin-film is permeable to ions.
Claims20
A thin-film electrochemical device, comprising:
- a monolithic substrate, which includes a cavity enclosed by bottom and side surfaces of the substrate;
- and
- a thin-film arranged on a top surface of the substrate and enclosing the cavity, wherein the thin-film is permeable to ions.
A method of producing a thin-film electrochemical device, the method comprising:
- providing a substrate;
- forming, from a top side of the substrate, a cavity in the substrate, wherein the cavity is enclosed by bottom and side surfaces of the substrate;
- and
- depositing an ion-permeable thin-film on a top side of the substrate, wherein the ion-permeable thin-film encloses a top side of the cavity and the ion-permeable thin-film allows ions from an environment in which the ion-permeable thin-film electrochemical device is arranged to pass into the cavity or allows ions from the cavity to pass into the environment.
