mems microphone stethoscope schematic

Abstract

This article is devoted to the investigation of MEMS microphone characteristics as an acoustic transducer of the electronic stethoscope. STMicroelectronics digital microphone MP45DT02 parameters were considered and significant physiological sounds were recorded. Also data obtained from MEMS and analog microphones were compared.The traditional acoustic stethoscope has been in use for nearly 200 years, changing very little over that time. As one of the most important diagnostic tools in a doctor s ....etc

Present and Future Electricity Storage for Intermittent Renewables


Energy Storage Technologies
Electricity is not usually stored per se. Energy storage technologies instead convert electricity to other energy forms (gravitational, pneumatic, kinetic, chemical), with a characteristic turnaround efficiency usually driven by the simplicity or complexity of conversion and reconversion between electricity and the stored energy form. For example, it can be 90-95% efficient to convert el ....etc
