Using biosensors to deliver personalized doses of antibiotics

A team of eight EPFL students has come up with a portable biosensor that can measure the amount of vancomycin in a patient's blood stream, enabling doctors to better control the dosage and reduce harmful side effects. Their ...

Biodegradable microsensors for food monitoring

A new generation of microsensors could provide the vital link between food products and the Internet of Things. ETH researchers have developed an ultra-thin temperature sensor that is both biocompatible and biodegradable.

Photopower for microlabs

Miniaturized devices such as microsensors often require an independent, equally miniaturized power supply. Searching for suitable systems, Japanese scientists have now developed a fully integrated microfluidic device that ...

Squeezed light produced using silicon micromechanical system

One of the many counterintuitive and bizarre insights of quantum mechanics is that even in a vacuum—what many of us think of as an empty void—all is not completely still. Low levels of noise, known as quantum fluctuations, ...

First precise MEMS output measurement technique unveiled

The commercial application of MEMS, or micro-electro-mechanical systems, will receive a major boost today following the presentation of a brand new way to accurately measure the power requirements and outputs of all existing ...

Novel sensors to detect molecules for medicine and agrifood

(Phys.org)—Agribusiness and medicine are constantly seeking more efficient methods for detecting biomolecules. To meet this need, a novel concept of miniaturized sensors has been developed by researchers from LAAS-CNRS ...

Sensor

A sensor (also called detector) 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-in-glass 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, most sensors are calibrated against known standards.
