Wearable technology today has made inroads into diverse fields such as navigation systems, advanced textiles, entertainment, and healthcare. The integration of wearables into healthcare, in particular, has been a focus of intense research and development in recent times. Thanks to advancement in electronics, healthcare wearables are gaining in popularity. With plenty of medical applications for…

For many countries, such as India, the adoption of the Internet of Things (IoT) will require customized features to make it fully accessible and affordable. For example, one recently conducted survey suggests low-power extensive area network (LPWAN) innovations — such as Long Range or LoRa — can offer large-scale and lower-cost connectivity to IoT devices…

The Regional Comprehensive Economic Partnership (RCEP), a proposed free-trade agreement (FTA) between several member states of the Association of Southeast Asian Nations (ASEAN), can take credit for about 85 percent of India’s total information and communication technology (ICT) imports during 2016-17. But this percentage dropped to 74 percent in 2018 because of a 15 percent…

In the previous tutorial, we discussed different types of batteries. Apart from reusability and battery chemistry, how a battery is packaged is an important factor, as it should be accommodable in a device without compromising safety norms. The geometry and size of a battery also plays a vital role in its application to a circuit.…

The advanced digital era is here. People are shifting from digitalization to remote connectivity. This means the use of automated controls between connected devices (via the Internet of Things) and equipment that’s driven by data intelligence and AI. This is happening in multiple sectors including those integral to public security, such as defense, energy, agriculture,…

With NASA announcing its preparedness to roll out the first all-electric aircraft called X-57 Maxwell or Mod II, the spotlight is on the next level technologies for the aeronautics sector. For this latest version of the aircraft, the typical combustion engines have been replaced with electric cruise motors. The development has opened the floodgates of…

In the previous article, we discussed different types of power supplies. For prototyping and testing circuits, the linear regulated power supply is the most economical and feasible do-it-yourself solution. The power output from a linear regulated supply can also be adjusted with the help of a variable resistor. Electronics hobbyists and beginners who do not…

2G networks will be soon a thing of the past, as will the GSM/GPRS modems based on it. In the past few years, 2G modems such as the  SIM800 and SIM900 from SIMcom have been popular in embedded systems, particularly hobby projects. As the telecom sector moves forward, 4G has pretty much become the norm.…

Given the high fuel costs for taxis and other vehicles, batteries typically offer drivers long-term savings compared to imported fossil fuels petrol or diesel. Plus, there are the environmental benefits of going electric. Although electric vehicles (EVs) are still pricey with fewer options available, that is changing. Startups and mobility companies are heavily investing in…

In the previous articles, we discussed passive electronic components like resistors, capacitors, inductors, and transformers. The passive components are particularly useful in designing various analog circuits. The real fun of modern electronics begins with semiconductors and digital electronics. Electronics is all about signals (in the form of voltage or current) and processing signals by components…

Technology has had transformative effects on the world, and in the lighting industry, it has brought about revolutionary changes. The push for technology has been propelled by the need for efficient, affordable, and environmentally sustainable sources of energy for the rapidly expanding limits of cities that now accommodate around 55 percent of the world’s population…

Fifty-six corporations moved production facilities out of China between April 2018 and August 2019. However, only three of those companies relocated to India and two set-up manufacturing facilities in Indonesia. According to a report by Nomura, a Japanese financial organization, the majority moved to Vietnam and a good portion went to Taiwan and Thailand. One…

In the previous article, we discussed the classification of transformers by core material, geometry, and voltage levels. The transformers can also be classified by their application and use. Let’s explore the two broad categories of use cases first  – transformers used in the electrical domain and transformers used in the electronics domain. The transformers used…

Consumer electronics startup, boAt, received INR 16 Cr (about USD2 Mn) in debt financing from investment lending firm, InnoVen Capital. The startup also recently acquired USD2.9 Mn in venture debt from Sachin Bansal’s BAC Acquisitions. Founded by Aman Gupta and Sameer Mehta in 2016, boAt is a technology company that manufactures electronics products in India…

In the previous article, we learned about the basic concepts of a transformer. A transformer is simply a pair of inductors magnetically coupled to enable electromagnetic induction between them. With the help of transformers, AC voltages can be stepped up or down at low costs without any hassle. Stepping up or down DC voltages requires…

One of India’s most comprehensive software exporters, Tata Consultancy Services (TCS), recently launched a new robotic process automation (RPA) solution for greater accuracy and reliability in chip fabrication. RPA will also help semiconductor businesses with digital transformation. TCS has set up a unique Semiconductor Centre of Excellence (CoE) to design closed-loop systems that connect analytics…

In the previous articles, we learned about resistors, capacitors, and inductors. When discussing inductors, we had talked about mutual inductance, which is the result of magnetic coupling between two inductors. If two inductors are used in a circuit to function as ‘inductors,’ this mutual inductance or any magnetic coupling between the two inductors is generally…

Dronstudy.com is an e-learning platform designed to further education in India. Educating in the traditional brick-and-mortar fashion is challenging with the growing population of young people. The Surat-based ed-tech startup Dronstudy went on to built a foundation to create a repository of online and offline audio-visual educational content enriching the learning endeavors of city and…

We have already learned about working with, types of, and applications of inductors. In the previous article, we have previously discussed selecting an inductor for a given circuit or application. For picking up the right inductor, it is important to know about reading inductor packages. There are many types of inductors that come in a…
