Simply stated, a magnetic field is analogous to electrical voltage, while magnetic flux is analogous to electrical current. A magnetic circuit is analogous to an electrical circuit with important differences. Electromotive force in an electrical circuit corresponds to magnetomotive force. Resistance and its reciprocal, conductance, in an electrical circuit corresponds to reluctance and its reciprocal, […]

Cybersecurity testing in 5G automotive designs
Special instrumentation can help bullet-proof the communication equipment powering next-generation vehicles. Craig Hendricks, Anritsu Co. The roll-out of 5G is bringing a host of real-time Internet-of-Things (IoT) capabilities to automotive designs. Use cases such as enhanced Mobile Broadband (eMBB, high-data-rate use cases for 4G LTE and 5G NR services that allows a high data rate […]
New ferroelectric material could boost piezoelectric actuator technology
If you’ve used an ink-jet printer or a tiny hearing aid, chances are those devices have employed lead-zirconium-titanium oxide (PZT, Pb(Zr,Ti)O3) piezoelectric ceramics as a means of generating ink droplets and amplified audio. These and numerous other applications have long used actuators and sensors employing piezoelectric materials which deform in response to an applied electric […]
Who is driving the growth of Virtual Reality?
Caltech Many leading research groups like the NASA Jet Propulsion Lab at the California Institute of Technology (Caltech), which helped send the Curiosity rover to Mars, and other leading academia are supporting VR development. Many heavyweight tech companies such as Microsoft, NVIDIA, Qualcomm, and IBM are investing in VR. Caltech is using VR to improve […]
Using energy harvesting to power wireless IoT nodes and wearables
Three elements are necessary to effectively implement energy harvesting (EH) into wireless IoT nodes, wearables and similar low-power applications. First, it a detailed power profile needs to be developed that considers active and sleep modes to produce a realistic estimate of the average power consumption. The power profile is used to size both the harvester […]
How are we tapping into the potential of VR?
Virtual Reality (VR) technology was primarily used by video gamers to play 3-D games. Not anymore. The technology has changed so much over the years that now medical, sports, training, industrial, and many more applications use it. And it has significant business potential. So what is VR? Manufacturer STMicroelectronics has spent a great deal of […]
Energy harvesting devices and ambient energy availability
Various forms of ambient energy are available in most environments. Depending on the environment and the power needs of the device, common energy harvester choices include light harvesters, thermoelectric harvesters, and mechanical vibration harvesters. Each of these energy harvesting technologies can be optimized for maximum performance in a given environment. In the case of light […]
Next-generation shielding may absorb electromagnetic interference rather than reflect it
Engineers trying to shield RF-sensitive circuitry a few years from now may have the option of using material that absorbs RF energy rather than just reflecting it. So say researchers at Drexel University and the Korea Institute of Science and Technology. They are researching a class of material called MXenes, and more specifically, titanium carbonitride […]
