Environmental monitoring is an interesting opportunity for flexible and printed electronics. The idea of putting low-cost sensors into buildings to monitor temperature, humidity and other environmental factors is promising. As a leader in passive humidity sensors, InviSense AB is making this happen. Recently, InviSense AB announced that it is partnering with Ynvisible Interactive Inc., establishing Ynvisible as the preferred manufacturing partner for InviSense’s expanding range of humidity sensors. The companies jointly announced that the first result of this collaboration will be the roll-to-roll production and delivery of InviSense’s humidity sensor for flat roofs.
