Highly stretchable and robust antennas are fabricated by injecting liquid metal into a microfluidic channel that consists of two types of silicone rubber with different stiffness. The resulting antennas exhibit high mechanical stability under strain, while retaining high stretchability; these antennas can be stretched by up to a tensile strain of 120 % with little degradation in radiation efficiency.
