In addition, there are four drawbacks associated with thermal drive materials. Firstly, the selection of materials is limited due to the limited availability of suitable options. Secondly, a high temperature is required for these materials to function, necessitating a high heat source. Thirdly, thermal drive materials are prone to deformation or destruction in high temperature environments, making material stability a crucial consideration. Finally, the manufacturing cost of thermal drive materials is currently prohibitively high and requires further reduction
