This article reports that it is possible to make multifunctional sensing devices with ZnO\ninfiltrated polymers while the sensing interactions could occur throughout the polymer. As such,\nwe find that infiltrated devices with SU-8 polymer can result in highly sensitive UV sensors. Mesh\ndielectric core devices were found to make sensitive gas sensors with a better than 5 ppm sensitivity\nfor formaldehyde and NO2. A new type of p-n junction device is further demonstrated that is\nsensitive to UV illumination, thus making it an enhanced UV sensor. Sensing devices relying on\nvolume interactions, such as light absorption, can significantly benefit from the infiltrated polymer.\nIn contrast, devices that rely on surface interactions, such as gas sensors, do not gain performance\nin any significant way with or without the infiltrated polymer.
