The present invention relates to core shell liquid metal encapsulates comprising multi-functional ligands, networks comprising such encapsulates and processes of making and using such encapsulates and networks. When subjected to strain, such network's conductivity is enhanced, thus allowing the network to serve as a healing agent that restores at least a portion of the conductivity in an adjacent conductor.

Core shell liquid metal encapsulates comprising multi-functional ligands and networks comprising same

The present invention relates to substrates comprising a network comprising core shell liquid metal encapsulates comprising multi-functional ligands and processes of making and using such substrates. The core shell liquid metal particles are linked via ligands to form such network. Such networks volumetric conductivity increases under strain which maintains a substrate's resistance under strain. The constant resistance results in consistent thermal heating via resistive heating. Thus allowing a substrate that comprises such network to serve as an effective heat provider.

Substrates comprising a network comprising core shell liquid metal encapsulates comprising multi-functional ligands

The present invention relates to core shell liquid metal encapsulates comprising and processes of making and using such encapsulates and networks. The shell(s) of such encapsulates employ a palette of materials having widely varied band structures and/or the desired spin pairing and/or bond polarization. Such encapsulates can be designed to respond to one or more stimuli of choice, including but not limited to electromagnetic, thermal, mechanical, photonic, and/or magnetic and are environmentally robust.

Liquid metal encapsulates having non-native shells

The present invention relates to articles comprising core shell liquid metal encapsulate networks and methods of using core shell liquid metal encapsulate networks to control AC signals and power. Such method permits the skilled artisan to control the radiation, transmission, reflection and modulation of an AC signal and power. As a result, AC system properties such as operation frequency, polarization, gain, directionality, insertion loss, return loss, and impedance can be controlled under strain.

Articles comprising core shell liquid metal encapsulate networks and method to control alternating current signals and power

Articles and methods of detecting an impact on an article using a resistor containing core shell liquid metal encapsulates are disclosed. Such core shell liquid metal encapsulates enable simple but robust impact sensors as such encapsulates comprise a highly electrically resistant metal oxide shell that prevents such encapsulates from coalescing. Yet when such shell is ruptured, the highly conductive bulk liquid metal is released. Such liquid metal changes electrical properties of a sensor comprising core shell liquid metal encapsulates which in turn is evidence of the aforementioned impact.
