Wearables or Wearable Technologies ?

This use case describes the industry of Wearable Technologies and more specifically, the use of heat flux sensors in Wearables.  This document will give you a broad overview of Wearable Technologies and more precisely, the application of heat flux sensors in Wearables and MedTech applications.

What are Wearables or Wearable Technologies?

Wearables definition

The term “Wearable” or “Wearables” or even “Wearable Technologies” describe all various technologies that employ electronic devices that can be worn as accessories, integrated into clothing, or even implanted or tattooed in the user’s body or skins. [1,3]

The industry of Wearable Technologies kicked off in 2014 with the development of smartphones and low energy bluetooth that allowed those products to develop fast. The industry of wearable technologies comprises various product categories from E-textiles, hearables, extended & virtual reality (ER & VR), to smartwatches. The growth of wearable technologies industry accelerated in recent years despite the COVID-19 represented by the launch of the 7th generation of the Apple watch in 2021. [2]

The rapid adoption of such technologies has placed wearable technology at the center of the Internet of things (IoT). Indeed, throughout the years, devices computing abilities, features and the sensors incorporating them have been multiplied driven by the advances in allied technologies such as wireless communication, computation and miniaturization.

and sensor technology thereby making smart devices central to diverse and disruptive applications, particularly related to monitoring, tracking and analytics. The emergence of wearables that contain multiple sensors has further augmented the capabilities of monitoring, sensing, tracking and data analytics, especially in the fields of Health & Wellness and Sport & Fitness.


  • Non-invasive measurement
  • Remote measurement
  • Real-time data collection
  • Suitable for a broad range of applications for Health & Wellness and Sport & Fitness.


  • Limited Battery Life (up to 6 days).
  • Storage of data requires internet connection (Cloud).
  • Bluetooth connectivity
  • Waterproof not always guaranteed.
