Contactless measurement of torque
Mechatronics, 2000Abstract This paper describes a micromechanical sensor for contactless detection of torque at rotating shafts. The sensor consists of a silicon chip and uses a magnetoelastic principle for measurement. A closed magnetic loop is formed by the sensor chip and a magnetoelastic layer which is applied to the shaft.

Contactless Nerve Stimulating Transducer
IEEE Transactions on Biomedical Engineering, 1972Stimulation of nervous tissue by means of an induced electric field produced by a contactless device is described. The unit is unique because it lends itself to surgical implantation.

Contactless photoconductive terahertz generation
Optics Letters, 2011We describe a pulsed terahertz (THz) emitter that uses a rapidly oscillating, high-voltage bias across electrodes insulated from a photoconductor. Because no carriers are injected from the electrodes, trap-enhanced electric fields do not form. The resulting uniform field allows excitation with a large laser spot, lowering the carrier density for a ...

Contactless abnormal gait detection
2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011We present a new method to detect abnormal gait based on the symmetry verification of the two-leg movement. Unlike other methods requiring special motion captors, the proposed method uses image processing techniques to correctly track leg movement. Our method first divides each leg into upper and lower parts using anatomical knowledge.

2015 IEEE MTT-S International Microwave Symposium, 2015
Radar technologies are emerging for health monitoring. The possibility of characterizing speed and distance in a contactless way opens up a range of practical applications, such as allowing elderly to reside longer in their familiar environment. Research has been focusing at first at single radar solutions targeting vital signs monitoring and detection

The Contactless Electromagnetic Sonotrode
2019Ultrasonic pressure waves generated using a tuned electromagnetic induction coil, promote cavitation in alloy melts as an alternative to the immersed sonotrode technique. The method targets the same benefits offered by traditional UST (degassing, microstructure refinement, dispersion of particles), but without some of its drawbacks.

Contactless directional crystallization
Journal of Crystal Growth, 1999A new method for crystal growth under reduced gravity conditions is proposed. The method combines the advantages of the Bridgman and floating zone techniques. The development of the method arose from the desire to obtain a melt configuration that is contained in a cylindrical ampoule but does not contact the lateral ampoule walls.

The introductory part of the chpater refers to the expansion of digital payments as a consequence of the spread of coronavirus and measures to protect the population. A detailed but not too broad definition of cryptocurrencies also describes the legal background, comparing digital money with traditional monetary obligations and classic money.
