A wearable vibration sensor for accurate voice recognition

A voice-recognition feature can be easily found on mobile phones these days. Oftentimes, we experience an incident where a speech recognition application is activated in the middle of a meeting or a conversation in the office. ...

Sensors and metrology as the driving force for digitalization

Many digitalized processes depend on data collected by increasingly powerful sensors and other test and measurement technology. When this data is processed, it provides precise and reliable information about the operating ...

Sensor

A sensor is a device that measures a physical quantity and converts it into a signal which can be read by an observer or by an instrument. For example, a mercury thermometer converts the measured temperature into expansion and contraction of a liquid which can be read on a calibrated glass tube. A thermocouple converts temperature to an output voltage which can be read by a voltmeter. For accuracy, all sensors need to be calibrated against known standards.
