The Directorate has contributed significantly to the Integrated Sensor is Structure (ISIS) project managed by DARPA which is a project to develop a missile tracking airship. In June 2008, the Air Force announced that scientists working for the Sensors Directorate had demonstrated transparent transistors. These could eventually be used to develop technologies such as "video image displays and coatings for windows, visors and windshields; electrical interconnects for future integrated multi-mode, remote sensing, focal plane arrays; high-speed microwave devices and circuits for telecommunications and radar transceivers; and semi-transparent, touch-sensitive screens for emerging multi-touch interface technologies."
