ENCAPSULATED DEVICE WITH INTEGRATED GAS PERMEATION SENSOR

摘要

An encapsulated device comprising an integrated gas permeation sensor is provided, comprising a base substrate with an electronic component arranged thereon being enclosed within an encapsulation for protecting the electronic component from moisture and/or oxygen; at least one sensor is arranged within the encapsulation to measure the permeation of gas into the encapsulation; each sensor comprises an electrically conductive sensing element comprising a moisture and/or oxygen sensitive material, wherein the reaction of said material with moisture and/or oxygen results in a change in the electrical resistance/conductivity of the sensor.
