Electro-hydraulic muscles are sometimes a viable alternative to electric motors in robot legs, according to researchers at Max Planck ETH Center for Learning Systems. This sort of electricity-to-movement transducer uses a liquid-filled bag with electrodes on opposite faces. A high potential difference across the electrodes pulls them together, squashing the liquid out of the way – and that action can ...
Following on from acquiring Numeca and Pointwise, Cadence Design Systems has introduced suite of computational fluid dynamics (CFD) software for vertical markets including automotive, turbomachinery, marine and aerospace. Called Fidelity, it “introduces a next-generation flow solver featuring high-order numerics, scale-resolving simulations and massive hardware acceleration”, according to Cadence. Included are specialised flow solvers for marine and turbomachinery applications, as well ...
Powerbox is aiming at data centres that use electronics flooded in liquid for cooling – so called ‘immerged applications’ – with a mains-to-12Vdc power supply. Called OFI600A12, it is the result of two years research and development, according to the firm: “Beside requiring a new mechanical approach to facilitate fluid circulation through and around the power supply, designers had to ...
Microfluidics is a viable route to making graphene-based opto-electronics, claims the University of Exeter. The aim is to exploit flakes of graphene and other 2D materials suspended in microfluidic structures which can be coupled to CMOS photonic circuits. The fluids in the micro-channels are liquid crystals, which can be controlled to physically hold optically-active graphene oxide flakes in position to ...
