Abstract: According to embodiments of the present invention, a sweat sensing device is provided. The sweat sensing device includes a continuous piece of hydrophilic paper including a first region for receiving sweat, a second region opposite the first region, and a third region therebetween; a flexible hydrophobic film having an opening; and a sensor unit. The hydrophobic film and the hydrophilic paper are arranged adjacent to each other with the opening aligned to and exposing the second region. The sensor unit is configured to facilitate a measurement based on the diffused sweat. The hydrophobic film and the hydrophilic paper are collectively folded in a stacked manner such that the sensor unit is sandwiched between the third and second regions. The hydrophilic paper is adapted for the received sweat to diffuse laterally along the hydrophilic paper. According to further embodiments, a method for forming the sweat sensing device is also provided.

Abstract: A photovoltaic cell comprises first and second electrode layers, an organic photoactive layer between the first and second electrode layers, and a polymeric grating structure in the first electrode layer. The first and second electrode layers are configured to collect electrical charges from the photoactive layer and to allow light to transmit through the first electrode layer to reach the photoactive layer. The grating structure is configured to provide a grating periodicity of about 100 nm to about 500 nm and grating amplitude of about 100 nm to about 500 nm. A device comprising the photovoltaic cell is disclosed. A photovoltaic cell may be formed by printing a polymer on a substrate to form a grating structure, forming a first electrode layer on the polymeric grating structure and the substrate, forming an organic photoactive layer above the first electrode layer, and forming a second electrode layer above the photoactive layer.
