Minnesota Patent of the Month – February 2022

Electrochromic devices take advantage of electrical fields to change colors or transmissivity. Sage Electrochromics, Inc. are experts with electrochromic materials. They have used these changeable properties to create smart glass which can reduce energy consumption and improve personal well being while still providing a view of the outdoors. Controlling the transmissivity can reduce glare while still offering a view outdoors.

Recently, they have expanded this technology to be waterproof. Their moisture resistant device has been designed to restrict moisture permeation from the external environment. This is achieved using a series of conductive and encapsulation layers which separate the electrochromic stack from the ambient environment. The encapsulation layer is the only exposed layer and runs over the edge of the device to create a sealed divide from the ambient environment. 

This moisture barrier allows the electrochromic device to be used in a wider array of applications without worry of moisture related failure. The company’s glass can currently change between clear, blue, green, and gray as well alter the transmissivity of each to let more or less light in. This can provide the beloved daylight without the annoying glare and without excessively heating a room. This electrochromic glass can transform energy efficiency in any building, and now, without worrying about the rain.
