A study of the use of micromachines, actuators, and sensors in yarn and fabric manufacturing will combine microelectronic mechanical systems and small scale robotic device to automate the process of repairing broken warp ends. Microelectromechanical systems integrate mechanical components, sensors, actuators, and electronics on a common silicon substrate using microfabrication technology. Integrated circuit process sequences manufacture the electronic components, whereas compatible micromachine processes that selectively etch away parts of the silicon wafers or add new structure layers form the mechanical and electromechanical devices. Such systems can improve precision of warp stop motion devices while minimizing machine downtime. 7 refs.
