This paper describes a novel MEMS resonant accelerometer based on two weakly coupled resonators (WCRs) using the phenomenon of mode localization. To the best of the authors' knowledge, it is the first time that this principle is experimentally demonstrated for an accelerometer. When acceleration acts on the two proof masses, there will be a differential electrostatic stiffness perturbation introduced...
This paper reports a new design for an electrostatic actuated microgripper with a ratchet self-locking mechanism. The self-locking mechanism enables long-time gripping without continuously applying the external driving signal, such as an electrical, thermal or magnetic field, which significantly reduces the effect and damage on the gripped micro-scale objects that are induced by the external driving...
By using a thermal separator and a vortex mill, a cryogenic grinding system was established in which experiments were performed to grind scrap tire peels into fine powders. The new grinding device is more effective than mechanical mills such as the ACM pulverizer. The cryogenic grinding results also show that rubber products of sizes less than that 50 μm are difficult to attain. Sharp corners and...
