General Electric developed 3D technology for printing sensors inside jet turbines.

For General Electric, the Internet of Things is not only a refrigerator that orders products on its own, but also sensors that can transmit data online under extreme conditions — for example, inside jet engines. The company announced this development in early June.



They use Direct Write technology to print miniature sensors directly on the surface with special metallic inks. First of all, these sensors are designed to collect data in extreme conditions: jet engines, gas turbines and other hot, uncomfortable and hard-to-reach places.

They withstand mechanical stress and temperature of 1100 degrees Celsius. Sensors can help engineers better understand the processes occurring inside the machines, increase the reliability of engines, the safety of air travel, etc.



Direct Write technology was developed in the 90s, when DARPA - the American Center for Advanced Defense Development - was looking for opportunities to place electrical circuits on flexible surfaces, and is now used in electronics to produce mobile phone antennas.
