A flexible conductive paste and a flexible electronic device are provided, which relate to the technical field of new materials. The flexible conductive paste includes: 3% to 7% by weight of a film former; 20% to 50% by weight of a conductive powder; 25% to 45% by weight of a liquid metal microcapsule; 10% to 30% by weight of a solvent; 0.1% to 5% by weight of a curing agent; and 0.5% to 5% by weight of a functional additive. The wall of the liquid metal microcapsule is a coating resin, the core of the liquid metal microcapsule is a liquid metal. The melting point Tm of the liquid metal satisfies Tm&#x2264;T1. The film former has a molecular weight within a range of 15000 to 30000, and has a glass transition temperature Tg smaller than or equal to T1. T1 is a temperature at which the flexible conductive circuit manufactured by the flexible conductive paste is deformed. The flexible conductive circuit of the present disclosure can have better conductivity and better flexibility simultaneously.

Flexible conductive paste and flexible electronic device

The present disclosure provides a liquid metal conductive paste and an electronic device, and relates to a technical field of new materials. The liquid metal conductive paste provided by the present disclosure includes: 1%-50% by weight of a liquid metal microcapsule, 30%-80% by weight of a conductive powder, 1%-25% by weight of a base polymer and 10%-40% by weight of a solvent. A capsule wall of the liquid metal microcapsule is made of a coating polymer, and a capsule core is made of a liquid metal. Melting point of the liquid metal satisfies: the liquid metal is in a liquid state at least when the wire made of the liquid metal conductive paste is deformed. The present disclosure can achieve a better flexible wire.

Liquid metal conductive paste and electronic device

A liquid metal-based information identification system includes a recognizer and a smart tag. The smart tag is configured to record environment information of an environment where an article is located through a sensor, and to send the environment information to the recognizer via a flexible circuit. The flexible circuit is internally used by the smart tag and comprises a circuit made of a liquid metal provided with a microfluidic channel including a vacuum chamber. When the liquid metal is in a phase transition, the liquid metal enters the microfluidic channel in such a manner that the circuit made of the liquid metal is short-circuited or disconnected. The recognizer is configured to receive and analyze the environment information, and to download first information of an article production link to the smart tag.
