Everyone uses wearable technology to track and monitor their health, along with style factors. 

Wearable IOT devices are experiencing a surge in demand due to features like health tracking, early warning and predictive benefits. In a way, the technology has created a paradigm shift in health tracking and analysis. The deployment of IOT and wearables in healthcare has ensured that medical data can be easily extracted and shared in real time.

The wearable internet has completely altered how we keep track of personal health and lifestyle, with constant vigil over surrounding dynamics. Depending on the expert opinions and findings observed in reports collected from these wearable technologies, decisions can be made to alter lifestyle choices, behaviors, and attitudes. 

Wearable healthcare devices are must-have tech for health-obsessed individuals, as they contribute towards efficient health diagnosis and early warning. Some wearables have greatly helped save lives and the health of disabled consumers, elderlies and bolstered emergency medical interventions. Users adopt wearables to reveal their brand appeal while adding to personality and style accessories with these devices.    

History and Evolution of Wearables

The earlier prototypes of wearable devices include spectacles, wrist-watch, computers, mini transmitters, etc. There have been details such as the invention of the small computer to cheat during gambling by Edward Thorp and Claude Shannon in 1961. The calculator watch worn by Michael J. Fox’s character Marty McFly in the Back to the Future movie franchise is one of the identifiable wearable internet devices during the 1980s. 

Furthermore, the walkman (1980s), digital hearing aid (1987), heart monitor for athletes (1980s), wearable webcam (1994), Fitbit (2010s), Google Glass (2013), Apple watch (2015), Oculus virtual reality (VR) headset (2016), etc. are all considered internet of things wearables. Some of these devices were popular and active, while others like Oculus VR, failed to impress long-time users. However, Facebook company Meta has acquired and rebranded Oculus as Meta Quest to reinforce developing meta VR. These technologies combined the power of internet-enabled computers, cloud, big data, and ultra-fast processing into one system.     

There are much more research and development as well as experimentation being done in a bid to launch enhanced wearable internet. Some wearable innovations are seen in the products like Nadi x yoga pants, wearables to fix body posture, improve spine and back support, etc.
