1. A biomedical sensor, comprising:
- a substrate sheet;
at least one electrode printed directly on a first surface of the substrate sheet, the at least one electrode being provided with an electrolyte element to enhance electrical contact with a surface to be measured;
a hermetically sealed compartment disposed on a second surface of the substrate sheet;
at least one printable soft battery disposed within the hermetically sealed compartment, the hermetically sealed compartment comprising;
a first humidity-proof material layer between the second surface of the substrate sheet and the battery; and
a second humidity-proof material layer on a side of the battery opposite the second surface of the substrate sheet;
the biomedical sensor further comprising a venting opening extending through the second humidity proof material layer of the hermetically sealed compartment; and
a removable humidity resistant patch over the venting opening.

Abstract
A disposable self-powered biomedical sensor comprises a printed wet electrode on a substrate sheet. The wet electrode is provided with an electrolyte element to enhance the electrical contact with a surface to be measured. Moreover, a printed battery encapsulated in a hermetically sealed compartment is provided on the substrate sheet. The disposable self-powered sensor can be stored within an enclosure or a package which provides a proper atmosphere to prevent the drying of the electrolyte and prolong the shelf life of the sensors.
