The range of fabric products with such features is quite wide. It can be protective covers, parts of wearable devices, or even parts of the Smart Keyboard. However, the patent focuses more specifically on the use of the Apple Watch.
The authors describe material consisting of interwoven threads and microcircuits. As the basis can be used knitted fabric. As for electronic components, these can be audio outputs, tactile sensors or gas detectors. In general, the range of various sensors is almost unlimited. So, Apple can create “smart” watchbands.
It is impossible to talk about the exact release dates for such products, since this is only a patent application. It is still unclear whether Apple implements the idea.
