ME 659 Micro Pressure and Flow Sensors for Biomedical Applications
ME 659 Micro Pressure and Flow Sensors for Biomedical Applications (3). Application of microtechnologies to the development of practical pressure and flow sensors for biomedical applications. Overview of micro-fabrication processes and conventional flow/pressure sensing devices. Application-specific criteria supporting the need for miniaturization. Design principles and constraints. Students are required to design either a micro flow or pressure sensor for a specific biomedical application.
