Some devices, like thermionic valves, contain a cathode that requires heating up before the device can work. However, other devices do not require a hot cathode to function. These devices have two electrodes within a sealed glass envelope that contains a low-pressure gas like neon. With a sufficiently high voltage applied to the electrodes, the ..read more

IoT, or the Internet of Things, depends on sensors. So much so, there would not be any IoT, IIoT, or for that matter, any type of Industry 4.0, at all, without sensors. As the same factors apply to all the three, we will use IoT as a simplification. However, some basic definitions first. As a ..read more

Earlier, we had a paradigm shift in the industry related to manufacturing. This was Industry 3.0, and, based on information technology, it boosted automation, enhanced productivity, improved precision, and allowed higher flexibility. Today, we are at the foothills of Industry 4.0, with ML or machine language, M2M or machine-to-machine communication, and smart technology like AI ..read more

We depend on our five senses to help us understand the world around us. Each of the five senses—touch, sight, smell, hearing, and taste—contributes individual information to our brains, which then combines them to create a better understanding of our environment. Today, with the help of technology like ML, or machine learning, and AI, or ..read more

Most high-voltage applications like power inverters, modern electric vehicles, and industrial control systems use IGBTs or Insulated Gate Bipolar Transistors, as they offer high-efficiency switching. However, as power densities are constantly on the rise in today’s electronics, the systems are subjected to greater demands. This necessitates newer methods of control. Littelfuse has developed new TVS ..read more

High-voltage eMobility applications are on the rise. Traditionally, fuses are non-re-settable, and sometimes mechanical relays or contactors are used. However, that is now changing. Semiconductor-based re-settable fuses or eFuses are now replacing traditional fuses. These innovative eFuses represent a significant trend in safeguarding hardware and users in high-voltage and high-power scenarios. Vishay has announced a ..read more

Individuals are progressively integrating electrical components into nearly every system possible, thereby imbibing these systems with a degree of intelligence. Nevertheless, to meet the intelligence requirements posed by diverse business applications, especially in healthcare, consumer settings, industrial sectors, and within building environments, there is a growing necessity to incorporate a multitude of sensors. These sensors ..read more

If you are just entering the world of design, you will have to face a session of DFMEA some time or the other. DFMEA is an acronym for Design Failure Mode and Effects Analysis. In recent years, corporate settings are using DFMEA, a subset of FMEA or failure mode and effects analysis, as a valuable ..read more

Although we usually talk to other humans, our interactions with non-animated objects are almost always silent. That is, until the advent of the Voice User Interface or Voice UI or VUI technology. Now, Voice UI has broken this silent interaction between humans and machines. Today, we have virtual assistants and voice-controlled devices like Siri, Google ..read more

UWB is the acronym for Ultra-Wideband, a 132-year-old communications technology. Engineers are revitalizing this old technology for connecting wireless devices over short distances. Although more modern technologies like Bluetooth are available for the purpose, industry observers are of the opinion that UWB can prove to be more versatile and successful than Bluetooth is. According to ..read more
