Abstract

Highly-automated textile manufacturing equipment has the potential for integrating electronic components into fabric in a low-cost process. These electronic textiles (or e-textiles) have a wide range of potential applications in wearable computing and large-area applications, including medical monitoring, assistance to the disabled, and distributed sensor networks. This paper discusses the design and implementation of a large-scale e-textile that functions as an acoustic beamforming array. The paper conveys the implementation experience and gives results gathered from the prototype. Further, the primary implementation issues and guidelines for future development are identified.
