Intelligent devices termed as wearables can be embedded in clothing, implanted in the user's body, or worn as accessories. Wearables can be combined with IoT technology due to the downsizing of sensors and advancements in modern technologies such as Artificial Intelligence, Machine Learning, and Big Data Analytics.

The increasing buzz for the industry is the growing numbers of autonomous and electric vehicles that employ linked infrastructure. The Internet of Things refers to the connectivity of many devices over the Internet. MCU miniaturisation offers system designers a platform that mainly includes use-cases for novel, and emerging applications. This expanding ecosystem of IoT or connected devices, which includes smartphones, Smart TVs, tablets, home appliances, smart metres, and security systems, is expected to have a positive impact on the demand for IoT MCUs. Due to the miniaturisation of sensors and power sources as well as the ongoing development of dependable, seamless connectivity, wearable technology is projected to witness new business opportunities in the coming years.

One of the world's main centres for the production of automobiles is in North America. The expansion of the local economy positively affected both the sales of passenger cars and commercial vehicles. The American Automotive Policy Council 2022 states that American automakers heavily invest in research and development, and automotive microcontrollers are influencing the automotive industry by increasing the demand for 8-bit microcontrollers as vehicle production rises. 8-bit microcontrollers are motivated by hybrid and autonomous vehicles. ​The strong demand for high-end applications across key end-user industries has made the North American market one of the top consumers of microcontrollers.
