Liquid Metal Based Antenna for Wearable Electronic

In this paper, a liquid metal based antenna for wearable applications is presented. The proposed solution can be used as the basis for flexible and stretchable antennas. The concept has been prototyped in a loop antenna, using silicon tubing of a diameter of 1.5mm in diameter, in which Liquid Metal is injected. The antenna operational frequency has been initially tuned to 868 MHz, however the antenna can be easily tuned for 2.4GHz (ISM band), typically used by Bluetooth and WiFi.
