An Introduction to Analog ElectronicsThe world of electronics is all about electrical circuits, electronic components, and interconnected technologies. All these elements can be primarily categorized as digital, analog, or a combination of both. However, here we will be focusing on the basics of the analog category in detail. Analog electronics is a branch of electronics that deals with a continuously variable signal.
 
It’s widely used in radio and audio equipment along with other applications where signals are derived from analog sensors before being converted into digital signals for subsequent storage and processing. Although digital circuits are considered as a dominant part of today’s technological world, some of the most fundamental components in a digital system are actually analog in nature. 
Plastic Road: A Revolutionary Concept to Build the RoadsThe abundance of plastic waste dumped in the environment and its harmful effects call for an urgent action. In response, many countries have actively taken up the responsibility of recycling as much plastic as possible. There are different ways of utilising the recycled plastic, one of them is to utilise it for the construction of roads. 
 
India is one of the few countries which has already started the use of recycled plastic in road construction from the past few years. In fact, a government order in November 2015 made it mandatory for the road developers in the country to make use of plastic waste alongside bituminous mixes for road construction. On the other hand, some similar projects are being initiated by other countries as well.

Tech Tats: Innovative Transformation of Wearables Technology into Electronic TattoosWe all know that wearable gadgets have evidently become a part of the mainstream technology and we have also seen how Biohacking implants modify a human body like nothing else. However, there is a concept that lies somewhere between wearables and Biohacking which is “Electronic Tattoos” or “Biotech Tattoos”.

These tattoos are epidermal electronics or thin, flexible patches of rubber containing equally flexible electronic components in the form of silicon wires measuring a few nanometers in thickness. These are much similar to the tattoos that we used to find in the bubblegum wrappers as kids, however, these adhere to the skin in a different way. The electronic tattoos look like circuitry-filled stickers, which collect vital information of the body to monitor the health of the wearer.
