  • Method and system for making microcoils and product thereof
    Patent number: 11198958
    Abstract: Disclosed is a method for fabricating coils including the steps of providing a liquid droplet having a diameter on length-scales ranging from hundreds of micrometers to nanometers and bringing a fiber into contact with the liquid droplet, wherein the radius of the liquid droplet is sufficiently high in comparison to the bending elastocapillary length which is defined as where E is the Young's modulus of the elastic fiber, r is the radius of the fiber and ? is the interfacial tension between the droplet and surrounding medium, so that capillary forces induce the spontaneous winding of the fiber around the droplet, to fabricate a coil with a diameter in the range from hundreds of micrometers to nanometers. Also disclosed is a system for making microcoils and to the product thereof.
