英文摘要	This paper reports the use of dual-microcantilevers coupled by cruciform overhang to enhance the mass sensitivity for minor mass detection. Driven by a piezoactuator in air, each cantilever of the structure can resonate in two different modes (in-phase and out-of-phase modes), and the resonant amplitude-ratios are compared before and after a mass adding. Using this sensing strategy, the cross-shaped overhang of the coupled system, by weakening the coupling effect between the two cantilevers, provides two orders of magnitude enhancement in mass sensitivity without scaling down the cantilevers.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000327183000064&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Engineering, Biomedical; Engineering, Electrical & Electronic; Nanoscience & Nanotechnology; EI; CPCI-S(ISTP); 0
