Centipede-Like Metastrip Enables On-Demand Programmable Droplet Motion
Sergio Britto, Stefano Gonella
We demonstrate programmable, frequency-tunable and size-selective drop motion on an elastic metastrip substrate with a centipede-like array of cantilever resonators. Under harmonic…
Boosting lattice polarization Mixing the perspectives of geometry optimization and cell-augmentation
Pegah Azizi, Rahul Dev Kundu, Xiaojia Shelly Zhang +1
Topologically polarized mechanical metamaterials enjoy a special built-in asymmetry that manifests as a preferred localization of edge states on selected edges. While this property…
Drops on architected elastic substrates: A repertoire of regimes at the turn of a knob
Sergio Santos, Zakari Kujala, Sungyon Lee +1
Drops on a vibrating substrate can experience a variety of motion regimes, including directional motion and climbing. The key ingredient to elicit these regimes is simultaneously a…
Programming droplet motion using metamaterials
Mohammad Charara, Zak Kujala, Sungyon Lee +1
Motion control of droplets has generated much attention for its applications to microfluidics, where precise control of small fluid volumes is an imperative requirement. Mechanical…
