Abstract
In certain examples, methods and devices, such as a soft electronics device, involve or include a first layer and a second layer from among the plurality of immiscible polymer layers, with the first and second layers integrated with one another to form a multilayered self-healing laminate, characterized in that polymer material in the first layer and polymer material in the second layer are cooperatively capable of autonomously recovering from at least one of the first layer and second layer being misaligned.
Claims21
An apparatus comprising:
- a plurality of immiscible polymer layers including immiscible polymer layers being characterized by having respectively different immiscible backbones;
- and
- a first layer and a second layer, each from among the plurality of immiscible polymer layers, the first layer and the second layer integrated with one another to form a self-healing laminate characterized in that polymer material in the first layer and polymer material in the second layer are cooperatively capable of autonomously recovering from at least one of the first layer and second layer being misaligned by the respectively different immiscible backbones providing interfacial tension-mediated realignment in response to certain of the immiscible polymer layers becoming misaligned.
An apparatus comprising:
- a plurality of immiscible polymer layers, among which are a first layer and a second layer integrated with one another to form a self-healing laminate characterized in that polymer material in the first layer and polymer material in the second layer are cooperatively capable of recovering from at least one of the first layer and second layer being misaligned by autonomously recovering from being misaligned and from at least one of the first layer and second layer being damaged, wherein the self-healing laminate is configured to act as a portion of electronic skin or as a cover for human skin or tissue.
A method comprising:
- providing a plurality of immiscible polymer layers including a first layer and a second layer integrated with one another to form a self-healing laminate;
- and
- using the self-healing laminate in an environment that subjects at least one of the first layer and second layer to being misaligned and continuing to use the self-healing laminate in response to the self-healing laminate autonomously recovering from being misaligned, wherein the self-healing laminate is to act as a portion of electronic skin or as a cover for human skin or tissue.
A method comprising:
- providing a plurality of immiscible polymer layers including a first layer and a second layer integrated with one another to form a self-healing laminate;
- and
- using the self-healing laminate in an environment that subjects at least one of the first layer and second layer to being misaligned and continuing to use the self-healing laminate in response to the self-healing laminate autonomously recovering from being misaligned, wherein the self-healing laminate autonomously recovering from being misaligned occurs in a state of manufacture of the plurality of immiscible polymer layers.
