This paper describes a new configuration of flapping wings to study the aerodynamic behavior of a micro UAV (unmanned aerial vehicle.) The flapping wings are composed of a pure parylene right wing and a PVDF-parylene composite left wing on purpose. The PVDF (polyvinylidene fluoride) sensor could only export the lift signals from the left wing. In comparison to the total lift signal picked by the load cell from the wind-tunnel facility, we can figure out and separate the lift contributions
