Abstract

The invention discloses a perovskite-like intermediate gel, preparation and a method for preparing electronic skin by using the perovskite-like intermediate gel, and relates to the field of material preparation and the field of the electronic skin. The problems that existing conductive materials are few in variety and high in preparation cost, and the prepared electronic skin is single in sensingfunction and complex in integration process are solved. The perovskite-like intermediate gel is prepared from organic amine halide, tin halide, gamma-butyrolactone and toluene. The preparation methodcomprises the following steps: ultrasonically dissolving the organic amine halide and the tin halide in the gamma-butyrolactone in sequence, stirring, and standing in the toluene atmosphere. The perovskite-like intermediate gel is used for preparing the electronic skin. The perovskite-like intermediate gel prepared by the preparation method has good conductivity and compatibility; the preparationmethod is simple in process and low in electronic skin preparation cost, widens the selection variety of electronic skin materials, and realizes a multifunctional flexible electronic skin sensor integrating stress, temperature and voltage detection. The perovskite-like intermediate gel is applied to the fields of material preparation and electronic skin.

Description

technical field [0001] The invention relates to the field of material preparation and the field of electronic skin. Background technique [0002] Electronic skin is an emerging cutting-edge technology, usually made of thin, flexible and stretchable, and conductive materials. They can mimic the functions and properties of human skin to convert external environmental conditions (pressure, strain or temperature) into electrical signals, which will help in the development of new biomedical sensors, intelligent robots and bionic prosthetics. Previous research on electronic skin mainly focused on single-function sensors, such as pressure sensors, strain sensors, or temperature sensors. However, achieving multiple responsive properties in one electronic skin device remains a great challenge so far. An important development trend of electronic skin is to achieve or exceed the multi-functionality of the sensory performance of human skin. In addition, it is also very important to d...
