Abstract
A blister pack for dispensing medication comprises a substantially flat backing, blisters formed on the backing, breakable resistive traces, conductive traces, a power source for applying electrical power to the traces, and a controller. The blisters and the backing form cavities for containing the medication, and each blister is coupled with another blister to form pairs of blisters. Resistive traces are applied to the backing under each blister. For each pair of blisters, the resistive traces under a first blister of the pair of blisters is connected in parallel by the conductive traces with the resistive traces under a second blister of the pair of blisters. The controller detects breakage of the resistive traces under the blisters for each pair of blisters by measuring the voltage across the resistive traces under each pair of blisters, and communicate the status to a remote server for instant analysis and reporting to parties of interest.
