Wearables technologies refer to electronic technologies that are embedded in wearables, such as smart bands, smartwatches, smart clothing, and smart rings. Wearable electronic devices are equipped with miniaturized electronic devices such as microchips and sensors, enabling them to perform computing tasks. The electronic devices embedded in wearables collect data and track activities, allowing the wearers to access information in real-time. The scope of the report includes smart bands, smartwatches, smart rings, wireless headphones, smart glasses, smart clothing, and head-mounted displays (HMDs).
