Abstract
Disclosed is a process to manufacture an environmental sensor. The process includes dispensing a dry powder material to a first area on a media element, wherein the powder material includes a plurality of microcapsules, each microcapsule encapsulating an environmental indicator material. The process further includes dispensing an adhesive to the media element. After the powder material and the adhesive have been dispensed to the media element, the powder material is in contact with the dispensed adhesive, and the adhesive holds the powder material in position.

A system for dispensing a powder material on a media element, the system comprising:
- a powder dispenser to dispense a predefined amount of dry powder material;
- a liquid dispenser to dispense a predefined amount of liquid;
- a wick dispenser to dispense a wick;
- and
- a control circuit communicable coupled to the powder dispenser, the liquid dispenser, and the wick dispenser, the control circuit comprising a processor and a memory, wherein the memory stores instructions executable by the processor to:
- dispense, by the powder dispenser, the predefined amount of powder material at a first area of the media element;
- dispense, by the liquid dispenser, the predefined amount of liquid at the first area of the media element;
- and
- position, by the wick dispenser, the wick on the media element, wherein at least a portion of the wick covers at least a portion of the first area.
