Smart technologies explained: AI, IoT, blockchain, smart homes, and more
Smart technology is transforming how we live, work, and interact with the world. From artificial intelligence and the Internet of Things to blockchain and quantum computing, these interconnected technologies are reshaping industries, cities, and daily life at an accelerating pace. This guide provides in-depth explanations of the core smart technologies driving this transformation, including generative AI, agentic AI, edge computing, smart homes, digital twins, and more.
We refer to smartworlders as individuals who have a general understanding and appreciation for the ways in which smart technologies are changing the world around us. They are aware of the benefits and drawbacks of these technologies, and they have a tendency to embrace new and innovative smart devices as they are introduced to the market. They are often early adopters of new smart technology products and are seen as trendsetters in the tech community.

Nanotechnology and the IoT: Boosting Efficiency and Capability
Nanotechnology can enhance the performance and capabilities of IoT devices by enabling the creation of smaller, more efficient, and more versatile sensors, antennas, and processors. These improvements can lead to greater accuracy, energy efficiency, and versatility in a variety of applications.
Machine Learning Innovations and Applications in Nanotechnology
Explore how machine learning impacts nanoscience and nanotechnology, leading to breakthroughs in material science, diagnostics, and energy solutions.
Decentralized Science (DeSci)
DeSci reimagines scientific research through blockchain, putting control in researchers' hands via decentralized funding, governance, and verification systems.
Big Data
Big Data is not about the data – it is about the value that can be extracted from the data: the harvesting of raw data from multiple, disparate sources, storing it for use by analytics programs, and using it to derive value in entirely new ways.
Blockchain Explained
Although it started with Bitcoin, blockchain technology extends well beyond cryptocurrencies to enable voting systems, anti-counterfeiting, supply chain security, medical records management, smart contracts, and much more.
Understanding Smart Contracts
A smart contract is a self-executing computer program with the terms of the agreement written directly into lines of code. It is stored and replicated on a blockchain network. Smart contracts enable the creation of trustless and decentralized systems.
Web3 Explained
Web3 represents the next major iteration of the Internet, built on decentralized technology and running on blockchains. It promises to shift control of data and digital assets from centralized platforms back to users.
DeFi Explained
Decentralized Finance (DeFi) is a global, open-source alternative to the current financial system, using blockchain and smart contracts to let users borrow, save, invest, trade, and access financial services without traditional intermediaries.
Smart Dust
Smart dust networks are a vision of the networked future where an intelligent network of trillions of minuscule sensors continuously feel, taste, smell, see, and hear what is going on in their surrounding environment.
Smart Cities Explained
What drives the emergence of smart cities now? What makes a city smart and what are its key elements? We look at some of the leading smart cities of the world.
How Nanotechnology Can Benefit Smart Cities
The development of smart cities can benefit from nanotechnology enabled materials and devices such as sensors, photovoltaics, efficient lighting systems, or communication networks.
Smart Grids Explained
The smart grid is an electricity network that uses digital and other advanced technologies to monitor and manage the transport of electricity from all generation sources to meet the varying electricity demands of end-users.
Smart Roads Explained
Part of smart transportation concepts, smart roads describe road infrastructure for autonomous or connected vehicles that is integrated with advanced network and communication technologies.
Smart Factory
A smart factory is a flexible system that can self-optimize performance across a broad network, self-adapt to and learn from new conditions in real or near-real time, and autonomously run entire production processes.
Digital Twin
A digital twin is a virtual representation of a physical object, place, process, product, or service. It uses real-time data and other sources to enable monitoring of systems, prevent problems before they occur, develop new management strategies, and improve decision-making.
Smart Home
A smart home is a residence that uses an automation system to remotely monitor and manage internet-connected home features like access control, security systems, lighting, climate, entertainment systems, and appliances.
Smart Home for Seniors
If a retirement home or some sort of care facility is not an option for your family, you will need to set up a support system that includes a residence outfitted as a smart home to accommodate your older relatives.
E-textiles and Smart Clothing – The New Black for the Internet of Things
The impact of technology on the textile industry is no longer limited to the design and production environment of clothing. Now, technology is becoming part of the textile itself.
Smart Toys
A lot of marketing hype has resulted in misconceptions about what a 'smart toy' actually is. We explain and show examples.
