Phase IV Engineering, Inc.

From our beginning in 1992, in Boulder, CO, Phase IV Engineering has been an innovator in wireless sensing. Our founder Rich Pollack started Phase IV as a “Skunk Works”, designing highly advanced and technically challenging sensors for Fortune 500 companies, NASA, the US military, and scientific research. We invented the world’s first battery-free RFID wireless temperature and pressure sensor. (Among many other applications,this sensor currently fliesinside the wheel valve stem of every Boeing 777 and 787 aircraft.) Phase IV has expertise in energy harvesting, RF design, low-power circuit design, and designing for very harsh environments. This over 100 years combined experience was a key reason our Phase IV Engineering team was recognized as the “Sensor Engineering Team of the Year” in 2015 bySensors Magazineand won “Product of the Year” in 2017 fromRFID Journal.
