Abstract

A system is provided for integrating conformal electronics devices into apparel. The system includes a flexible substrate onto which a flexible device is disposed. The flexible device can include a stretchable coil that can be used to receive and transmit near field communications. The flexible device also includes an integrated circuit component and a memory unit. In some examples, the device also includes a sensor that is configured to record measurement of the wearer of the apparel and/or the surrounding environment.
