In the last two decades, major progresses have been made in developing highly-exothermic reactive mixtures. Mixtures of metallic and oxide powders, so-called nanothermites have been used to release temperature, pressure waves and eventually new compounds through exothermic reactions. By varying the size and nature of the oxidizer, we can tune the performances of these materials and multiply the applications...
A novel wireless and passive temperature sensor that utilizes microfluidic and liquid metal technologies for the temperature-dependent modification of the sensor's radar echo is introduced. Liquid metal is used to dynamically alter the number of antenna elements activated along a linear array configuration with respect to temperature. In this way, the sensed temperature value can be accurately quantified...
