Wearable technology refers to electronic devices that are designed to be worn on the user`s body. These devices can take various forms, including jewellery, accessories, clothing, or even implants or tattoos on the skin. They are typically hands-free gadgets that are powered by microprocessors and have the ability to send and receive data via the internet. The history of wearable technology can be traced back to the 1990s when Canadian researcher Steve Mann invented the wearable wireless webcam, which paved the way for future IoT technologies. In the 2000s, there was an explosion in wearable technology with the introduction of Bluetooth headsets, Fitbits, and the Nike plus iPod Sport Kit. The 2010s marked a tipping point for wearable technology with the entry of Google Glass, the Apple Watch, and The Oculus Rift Headset. In the 2020s, the gaming industry continues to add newer augmented reality (AR) and virtual reality (VR) headsets, while clothing designers are rapidly bringing smart clothing to the mainstream. Wearable technology has a wide range of applications and is evolving into an important category of the Internet of Things (IoT). It has practical uses in various fields, including medicine, fashion, logistics, military, and more For example, in the military, wearable technologies such as boot inserts with sensors can help gauge how soldiers are carrying the weight of their equipment and how terrain factors impact their mission planning optimisation. In the fashion industry, wearable technology has opened up new possibilities for smart clothing and accessories. These technologies can be embedded in fabric or accessories, allowing users to track and monitor various aspects of their health and well-being. Overall, wearable technology is a rapidly growing field with the potential to revolutionise many aspects of our lives, from healthcare to entertainment
