Cheaper and faster coronavirus tests in the pipeline

A new sensor that can give an immediate response to the presence of coronavirus could dramatically improve the efficiency of testing and overcome some of the current surveillance bottlenecks, believe its Swedish developers.

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.
