Scientists from the Physikalisch-Technische Bundesanstalt (PTB) have implemented a novel pressure measurement method, partly as a byproduct of the work on the "new" kelvin. In addition to being new, ...

Highly accurate pressure sensors with long-term stability are necessary for fuel efficiency and reduction of harmful emissions. Increasingly demanding requirements of piezoresistive sensors include ...

Embedded in cell phones, rings, bracelets or watches, the novel tools aim to make it easier to manage hypertension. But they must still pass several tests before hitting the clinic. By Matías A. Loewy ...

A concept design showing what the team envisions as final products using the resonance sonomanometry blood pressure method. The device on the upper arm measures from the brachial artery and the ...
