OBJECTIVES Wearable systems can be broadly defined as mobile electronic devices that can be unobtrusively embedded in the user's outfit as part of the clothing or an accessory. In particular, unlike conventional mobile systems, they can be operational and accessed without or with very little hindrance to user activity. To this end they are able to model and(More)
In this paper, several issues concerning the development of textiles endowed with electronic functions will be discussed. In particular, issues concerning materials, structures, electronic models, and the mechanical constraints due to textile technologies will be detailed. The idea starts from an already developed organic field-effect transistor that is(More)
The future trend in wearable computing is to integrate electronics directly into textiles. Our approach is to use conductive textiles for signal transmission. We investigated the electrical performance of textile transmission lines. We present methods for measuring as well as for modeling the high frequency properties of textiles. With the results it is(More)
Embedding of electronics in clothing raises the demand for wireless interconnections for short distances. A lowpower transmitter-receiver concept of low-complexity is a crucial factor for maintaining low costs and battery life in a distributed on-body sensor network. This paper presents such a transmission system based on inductive coupling giving a(More)
In this paper several issues concerning the development of fibers endowed with electronic functions will be presented and discussed. In particular, issues concerning materials, structures, electronic models and the mechanical constraints due to textile technologies will be detailed. All these aspects have been studied in the framework of the project(More)
In our era of converging technologies, it is significant that the second Industrial Revolution should meet the first on common ground: textiles. Modern data processing is, after all, an offshoot of technology first introduced in the 18th century to automate the production of woven textiles. The punched-card system developed by J.-M. Jacquard in 1804 to(More)
This paper sketches the vision and first results of a 'Personal Health Assistant' PHA, opening up new vistas in patient centred healthcare. The PHA is comprised of a wearable sensing and communicating system, seamlessly embedded in daily clothing. Several on-body sensors monitor the biometric and contextual status of the wearer continuously. The embedded(More)
