Abstract: A fluid-induced vibration energy harvesting apparatus with a non-rotating bluff body is provided. The apparatus does not use a common design method of rigidly securing a bluff body to an elastic beam in a design of the bluff body, but adopts a manner of connecting the bluff body and the elastic beam through a rotating shaft and a connecting shaft. Because a kinematic pair at a connection position is a rotating pair, the bluff body will only vibrate transversely and will not rotate, thereby achieving an effect of increasing an amplitude at the same frequency, and finally realizing an increase of converted electric energy and improving the conversion efficiency.

Abstract: A smart retail product shelf liner called ‘MOOCA’ to detect product loads on its surface.

The smart liner is well suited for autonomous checkout systems. MOOCA is an origami-inspired low-cost configurable surface structure having conductive threads and copper wires integrated into the origami structure to detect and recognize product loads and thus to detect when products are either picked-up, or put-down, upon the smart MOOCA liner of the shelf.
