Abstract
Methods and devices for determining device usability, e.g., for point of care assay devices. In one embodiment, the invention is to a method of determining device usability in a sensing device, including the steps of: providing a device comprising a first electrical pad; a second electrical pad; and a first polymer layer contacting at least a portion of the first and the second electrical pads and a second polymer layer contacting the first polymer layer and not the first and second electrical pads; applying a potential across the first and the second electrical pads; measuring an electrical property associated with the first and the second polymer layers; and determining whether the measured electrical property associated with the first and the second polymer layers has exceeded a threshold level associated with the device usability.
