Design aspects of pipe belt conveyors

This dissertation investigates how to design a pipe belt conveyor system in a more effective way, considering two aspects: to ensure conveyor belt has sufficient bending stiffness to form an enclosed pipe shape without a contact loss with the idler rolls; and to reduce energy consumption of the system from the indentation rolling resistance. <br...

Electrothermal actuators for SiO₂ photonic MEMS

This paper describes the design, fabrication and characterization of electrothermal bimorph actuators consisting of polysilicon on top of thick (&gt;10 μm ) silicon dioxide beams. This material platform enables the integration of actuators with photonic waveguides, producing mechanically-flexible photonic waveguide structures that are...

Fabrication and characterization of suspended beam structures for SiO2 photonic MEMS

This paper proposes a microfabrication process for the reliable release of SiO2 beam structures. These structures are intended to be utilized in SiO2 photonic MEMS. A major fabrication challenge is the release of thick (>10 ?m) SiO2 structures with high yield. A single mask process is developed based on temporary reinforcement of the SiO2...
