According to SlashGear, any piece of clothing that is connected to a device through at least one sensor and some form of wireless communication can be considered smart clothing. The term also applies to clothing woven with electronic devices and similar "smart textiles", which are designed to sense and sometimes react to the environment. The purpose of smart clothing is to combine fashion with the advanced features that are usually offered to us by smart watches and smartphones.
A study published in 2021 by the Journal of Applied Physics identified three "major obstacles" to the standardization of e-textiles, including the flexibility of conductive wiring, the need to generate electricity, and garment production (the actual cutting and sewing of these garments by traditional means, as well as the treatment of moisture). The study also notes that few products are commercially viable enough to foster long-term support. However, there are now a few smart clothing products that deserve attention.
One of the most useful smart garments on the market right now is a pair of Sensoria smart socks, which the company claims can store and register data to help improve running efficiency. The smart components in these socks are able to record movement, while the socks are able to send this data to a second device. This data can be tracked on a separate smartphone app that can provide guidance on how to reduce stress on your feet.
Bluetooth enables wearables to perform low-power connectivity and basic data transmission without being as complex as using other wireless traffic standards, and it helps develop Bluetooth wearables with compact size, long battery life, and seamless connection to smartphones.
The Bluetooth BLE protocol can be perfectly applied to wearable devices for the following reasons:
The protocol is carefully optimized for ultra-low power consumption.
Low power consumption helps reduce battery size, resulting in lower product cost, size, and weight.
Since the BLE smart-ready host is used in the smartphone, it is easy to implement the protocol.
Wearables exchange small amounts of burst information at long intervals.
