Surface acoustic wave design fundamentals
Archives of Acoustics, 2014 This paper will provide a fundamental approach to the design of SAW transducers and filters. Although SAW devices are often modeled with complex and large programs, the basic design principles can be analyzed with simple programs and commercially ...

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection
Advanced Materials, EarlyView.Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Novel surface-acoustic wave transducers
Archives of Acoustics, 2014 The conventional means of launching a Surface Acoustic Wave on a piezoelectric substrate is by using an inter-digital transducer. A modified structure using multilayer deposition, but only a single critical photolithography stage, is proposed in this ...

Hybrid Liquid Metal Cathode Enables High‐Performance Intrinsically Stretchable OLEDs
Advanced Materials, EarlyView.We report a hybrid liquid metal (Hyb‐LM) cathode engineered via selective rupture of liquid metal particles (LMPs), forming a bilayer architecture with a surface liquid metal (LM) layer and underlying LMP layer, which has benefits of both LM and LMPs.
