With the progress of science and technology and the improvement of medical level, the life expectancy in the world is continuously prolonged. In this situation, as China's aging population is increasing, the design of products for the elderly is also getting more attention. Designers should actively explore the product needs of the elderly, truly feel their living needs and choose suitable household materials to be used in the design. The work aims to explore the properties and characteristics of new materials such as intelligent temperature- adjusting materials and intelligent light- adjusting materials. The new demands for the product materials proposed based on the physiological and psychological characteristics of the elderly are analyzed, and the main design points of the aging- friendly household products are put forward. On the basis of ensuring the practicability of household products, the safety and comfort degree of the elderly's life should be guaranteed. The feasibility of new materials applied in the design of aging- friendly household products is explored by taking into account the price bearing capacity of the users, and combining the analysis on the use cases of related materials in the current market, for the purpose of further improving the living conditions of the elderly and promoting the development of new material technology in the aging-friendly design.
