Washington State University researchers have developed chip-sized processors and 3D printed antenna arrays using copper nanoparticle ink that remain stable when bent or exposed to harsh conditions. Led by Professor Subhanshu Gupta and PhD student Sreeni Poolakkal, the breakthrough enables flexible wireless systems for aviation, automotive, and wearable technology, achieving real-time beam stabilization in a lightweight array of four antennas that scales to 16 total antennas.
