Functional Electronic Textiles: Circuit Integration and Energy Harvesting Power Supplies

This study presents a quantitative analysis of experimental data for extracting energy from human body motion and its possibility of powering portable electronic devices, such as consumer electronics or biomedical monitoring sensors. Since portable electronic devices are typically limited by the size and lifespan of batteries, energy harvesting shows potential as alternative for extending battery life. The acceleration was collected experimentally from 10 subjects while walking and running at different velocities on a treadmill. The acceleration results were studied and a figure of merit consisting of the acceleration-squared-to-frequency was found to determine, in addition to the quality factor, as the important factors for optimal energy harvesting. It was determined that from average walking an energy harvester can produce a power output density greater than 1mW/cm3.

This paper describes the early conception and latest developments of electroactive polymer (EAP)- based sensors, actuators and power sources, implemented as wearable devices for smart electronic textiles (e-textiles). Such textiles, functioning as multifunctional wearable human interfaces, are today considered relevant promoters of progress and useful tools in several biomedical field, such as biomonitoring, rehabilitation and telemedicine. This paper presents the more performing EAPbased devices developed by our lab and other research groups for sensing, actuating and energy harvesting, with reference to their already demonstrated or potential applicability to electronic textiles.

Textile Products

Test methods for smart or electronic textiles (e-textiles) are critical to ensure product safety and industrial quality control. This paper starts with a review of three key aspects: (i) commercial e-textile products/technologies, (ii) safety and quality control issues observed or foreseen, and (iii) relevant standards published or in preparation worldwide. A total of twenty-two standards on smart textiles – by CEN TC 248/WG 31, IEC TC 124, ASTM D13.50, and AATCC RA111 technical committees – were identified; they cover five categories of e-textile applications: electrical, thermal, mechanical, optical, and physical environment. Based on the number of e-textile products currently commercially available and issues in terms of safety, efficiency, and durability, there is a critical need for test methods for thermal applications, as well as to a lesser degree, for energy harvesting and chemical and biological applications. The results of this study can be used as a roadmap for the development of new standardized test methods for safety & quality control of smart textiles.
