Electrochemically driven mechanical energy harvesting [PDF]
Nature Communications, 2016 AbstractEfficient mechanical energy harvesters enable various wearable devices and auxiliary energy supply. Here we report a novel class of mechanical energy harvesters via stress–voltage coupling in electrochemically alloyed electrodes. The device consists of two identical Li-alloyed Si as electrodes, separated by electrolyte-soaked polymer membranes.

Mechanical harvesting of broilers
Poultry Science, 1998 At the end of the growout phase of broiler production essentially all broilers are caught and loaded into coops or cages entirely by hand. The catching of broilers remains one of the few aspects of broiler production not yet automated. Vacuum systems, permanent conveyors recessed in the floors of growout facilities, collecting mats, scoops, and self ...
