This study designed a vertical take-off and landing tailsitter unmanned aerial vehicle (UAV) with a long endurance time.Nine parameters of the tailsitter UAV were investigated.Using a 2k full factorial Projector Torch test, 512 experiments on the nine parameters were conducted at their maximum and minimum values.The time coefficient and air resista
Resonant micro/nanoelectromechanical systems (MEMS/NEMS) with on-chip integrated excitation and readout components, exhibit exquisite gravimetric sensitivities which have greatly advanced the bio/chemical sensor technologies in the past two decades.This paper reviews the development of integrated MEMS/NEMS resonators for bio/chemical sensing applic
