The need for non-invasive, real-time measurement of the density and speed of sound of a liquid led to the development of an ultrasonic sensing technique based upon the reflection of ultrasound at the solid-fluid interface.

The Pressure Sensor Mechanism is designed to measure or monitor tactile pressure. It is based on passive Radio Frequency Identification (RFID) sensor tags and is applicable to a variety of systems. As RFID sensors transmit information wirelessly, they eliminate many challenges associated with traditional wired systems...

In this week's Tech Briefs TV video, Rice University scientists demonstrated an ability to embed graphene into paper, cloth, and even your breakfast. Why etch patterns into toast? James Tour, a chemist at Rice University, envisions never-before-seen applications, like embedding electronics as a self-cooking heat...

A temperature sensor with practically no effect at all on the temperature of the object measured has been created in the laboratory by researchers at the University of São Paulo (USP) and the University of Campinas (UNICAMP) and is awaiting a patent for commercial production.
