    Abstract: An electrochemical device is described, including a first electrochemical cell, a second electrochemical cell, connected in series to the first electrochemical cell, and a biodegradable conductive adhesive may include a conductive additive and a copolymer including at least two polycaprolactone chains attached to a polymeric center block, where the polymeric center block may include polyvinyl alcohol, disposed between the first electrochemical cell and the second electrochemical cell. A biodegradable conductive adhesive includes a hydrogel which may include a copolymer having at least two polycaprolactone chains attached to a polymeric center block, where the polymeric center block may include polyvinyl alcohol. Implementations of the biodegradable conductive adhesive may include a conductive additive or a salt. The biodegradable adhesive can include a dried hydrogel, where the hydrogel is biodegradable.

    Abstract: A method for producing flexible conductive printed circuit with a printed overcoat is disclosed. For example, the method includes forming conductive printed circuit lines on a flexible substrate, detecting locations on the flexible substrate where the conductive printed circuit lines are formed, and printing an overcoat over the conductive printed circuit lines at the locations that are detected on the flexible substrate, wherein the overcoat comprises a mixture of thermoplastic polyurethane (TPU) and a solvent having a viscosity of 1 centipoise to 2,000 centipoise to allow the mixture to be printed.

    Abstract: There is described a point-of-purchase display and method. The display includes one or more sheets. The one or more sheets when unfolded and assembled form the display. The display includes a back wall, a front wall, at least a side wall and a bottom wall. A printed electronic device is affixed to a surface of the one or more sheets. The printed electronic device is selected from the group consisting of: wires, insulators, resistors, capacitors, inductors, transformers, transistors, antennas, OLEDs and sensors. A microcontroller electrically is coupled to the printed electronic device. A connection device is coupled to the printed electronic device. A modular electronic component is coupled to the connection device.

    Abstract: Systems and methods for detecting item placement on a surface are provided. The system includes a pressure-sensitive conductive sheet and a resistive grid connected to the pressure-sensitive conductive sheet. The resistive grid includes an electrically non-conductive polymer. The resistive grid includes one or more lines arranged in a pattern. The lines may include parallel lines, parallel and perpendicular lines, concentric circles, arcs of expanding radius, and/or any other suitable types of lines and/or any combination thereof. The resistive grid may include one or more distinct lines and/or shapes positioned at various points along the pressure-sensitive sheet layer.
