Scientists at the National Research Nuclear University MEPhI (NRNU MEPhI) have created a new contactless measuring system for the study of high-speed processes, which can be used in forensics and aerospace research.
The results of the study were published in the Journal of Applied Mechanics and Technical Physics.
According to the researchers, the introduction of contactless inductive sensors instead of traditional contact sensors will significantly improve the accuracy of measurements in ballistic tests in both air, solids and liquids.
The new system is portable and, as the authors of the study claim, can be used in forensic examinations, as well as in the development of aerospace protective equipment against collisions with man-made debris and micrometeoroids.
Scientists have explained that the sensors respond to changes in magnetic field energy and magnetic flux rate. The say the advantage of the new type of devices is the significant sensitivity, simplicity and durability of the design, plus the functioning of such a sensor does not require a power supply.
The research group plans to further develop methods for combining contactless inductive sensors and recording equipment for optical-photoelectric detection that will enable improved measuring techniques for carrying out difficult and expensive experiments.
