Abstract: Systems and methods for monitoring the status of air filters are provided. One or more thermoelectric sensors are provided to have an upstream sensing surface positioned adjacent the inlet surface of the air filter, and a downstream sensing surface positioned adjacent the outlet surface of the air filter. Sensing circuitry are connected to the thermoelectric sensors, configured to receive signals from the thermoelectric sensors and process the signals to obtain status information of the air filter.

Abstract: Flexible thermoelectric devices including an array of slot openings on a flexible substrate, and methods of making and using the same are provided. The slot openings on the flexible substrate can help remove the tension or compression induced during bending of the devices. Slot openings each extend along a cross direction substantially perpendicular to the longitudinal direction of the substrate.

Abstract: A flexible multilayer construction is configured for mounting an electronic device. The flexible multilayer construction includes electrically conductive spaced apart first and second pads for electrically connecting to corresponding electrically conductive first and second terminals of the electronic device. The first and second pads define a capillary groove therebetween that is at least partially filled with an electrically insulative reflective material by a capillary action.
