Stretchable polymeric heaters fabricated using soft and ultrastretchable elastomeric matrix
as the matrix material and liquid metal patterned conductor as the heating element.

The liquid metal is patterned using state-of-the-art printing technology, The heater can be operated by the principle of joule heating.
The heater can stretch manifold by virtue of the stretchability of the elastomeric matrix and the fluidity
of the liquid metal and yet demonstrate unhindered heating performances.

Due to the softness of the materials and the skin friendly materials used, the heater can very well conform to human skin and deform well in alliance
with human movements and thus is very promising for seamlessly operating in the field of thermotherapy for athletes even during extreme physical activities.
