In a performance application at wide open throttle, the ECU needs to control the air to fuel ratio to hit a small target somewhat richer than stoichiometric. The narrowband sensors most OEs use only ...

Abstract: Enabling broad use of electromagnetic energy harvesting in wireless sensor screws requires robust systems that work with weak vibrations and varying frequency profiles. This contribution ...

Abstract: A wideband acoustic sensor is reported in which the cantilevers are covered with an organic film in a piezoelectric micro-electro mechanical systems (MEMS) acoustic transducer. Coating the ...
