The method includes removing the wafer from the pedestal by the robot and measuring an exit offset. The method includes determining a magnitude and direction of the temperature induced offset using the entry offset and exit offset.

This invention relates to a liquid metal composite magnetic hydrogel with magnetic and thermal self-healing properties, its preparation method, and its applications. It addresses the problems of poor flexibility, weak electrical and thermal conductivity, and insufficient environmental tolerance in existing hydrogels. The method of this invention comprises the following steps: 1) preparing a liquid metal dispersion; 2) preparing a magnetic precursor system; 3) preparing a carrageenan solution; 4) magnetic field-induced orientation and thermal cross-linking curing; and 5) low-temperature induced formation of a double network. The gel material prepared by this invention exhibits thermal self-healing properties, achieving flame retardancy and self-healing even in extreme environments such as high temperatures and combustion, thereby ensuring the structural integrity and continuous stable function of the material. Simultaneously, by introducing liquid metal, the electrical and thermal conductivity of the gel system is improved, and by introducing magnetic components, it acquires magnetic control capabilities, enabling continuous use in extreme environments.
