On Oct. 31, 2014 at NASA’s Armstrong Flight Research Center at Edwards Air Force Base, in California, the Adaptive Compliant Trailing Edge (ACTE) flap was extended to 20 degrees deflection. Flight results will validate whether the seamless design with its advanced lightweight materials can reduce wing structural weight, improve fuel economy and efficiency, and reduce environmental impacts.

NASA test of shape changing wing design
Interesting concept. If this becomes an affordable technology, money to be saved all around
