The environment plays a critical role in the development, dissemination, and transmission of antimicrobial resistance (AMR). Pharmaceuticals and personal care products (PPCPs) enter the environment through direct application to the environment and through anthropogenic pollution. Although there is a growing body of evidence defining minimal selective concentrations (MSCs) of antibiotics and the role...
Distinct from conventional diaphragm-type pressure sensors, a bulk-type silicon-based pressure sensor is proposed and demonstrated. External hydrostatic pressure acting on the sensor is converted to biaxial compression inside an all-silicon encapsulated vacuum cavity, and measured using four piezoresistors oriented to optimally utilize the anisotropy of silicon piezoresistance. Limited only by the...
This paper outlines the approach to realize a MEMS pressure sensor suitable for meeting the stringent requirements of sensing in a downhole environment reaching 175-oC temperature and 200-MPa pressure while maintaining an accuracy of better than 0.02% for an extended measurement period of several weeks during oil and gas exploration. A few sensing structures are proposed and strategies for their optimization...
