Methods, systems, and devices are disclosed for collecting and transferring naturally-produced sweat containing an analyte to a biosensor and/or biofuel cell to estimate a concentration of the analyte corresponding to the analyte's concentration in blood and/or for producing electricity. In some aspects, a device includes a substrate, a plurality of electrodes disposed on the substrate and operable to detect an analyte in naturally-produced sweat of an individual, and a sweat permeation layer including a hydrogel, wherein the sweat permeation layer is in contact with the plurality of electrodes and configured to transfer the sweat containing the analyte through the sweat permeation layer to reach the plurality of electrodes for detection and/or energy harvesting.
