Title: Innovations of Wei Hong in MEMS Technology
Introduction
Wei Hong is a prominent inventor based in Ames, IA (US), known for his contributions to microelectromechanical systems (MEMS) technology. He holds 2 patents that showcase his innovative approach to pressure sensing using advanced materials.
Latest Patents
One of Wei Hong's latest patents is a high sensitivity MEMS pressure sensor. This invention features a microelectromechanical system that utilizes a graphene-based pressure sensor. The design involves transferring a large area of few-layered graphene onto a suspended silicon nitride thin membrane, which is perforated by a periodic array of micro-through-holes. Each through-hole is covered by a circular drum-like graphene layer, referred to as a graphene 'microdrum'. The unique aspect of this sensor design is that the introduction of through-hole arrays into the supporting nitride membrane generates increased strain in the graphene membrane. This occurs due to local deformations of the holes under applied differential pressure. The sensor demonstrates a gauge factor of 4.4 for the graphene membrane and a sensitivity of 2.8×10-5 mbar-1, with good linearity over a wide pressure range. This innovation outperforms most existing MEMS-based small footprint pressure sensors that utilize graphene, silicon, and carbon nanotubes as sensitive materials.
