The wearable heating device is becoming more and more noteworthy due to increasing interest in soft robots, flexible electronics, and skin-like sensors. Liquid metal is highly adequate for wearable electronic devices because of its metallic conductivity, high thermal conductivity, fluidic nature, and low toxicity. In this study, we fabricated a stretchable, flexible, and wearable polymeric heaters by employing liquid metal (LM, eutectic gallium-indium alloy) and carbonyl iron particles loaded liquid metal (CIP-LM) patterns that can generate thermal energy by Joule heating and induction heating. We utilized stencil printing and spray coating to pattern the LM and CIP-LM on two polydimethylsiloxane (PDMS, Sylgard-184 and Ecoflex 00-30) substrates. The thermal characteristic is demonstrated by LM inclusion and manipulated as a function of the CIP concentrations in the LM. This wearable heating device would be potential for applications in thermotherapy, and wearable devices. |
