TLDR
Simultaneous scavenging from different energy sources significantly increases the autonomy of a wearable system, in the meanwhile reducing battery size, by integrating a power management system and multiple diverse scavenging transducers and a storage module on a well-chosen textile antenna topology.Abstract:
Smart-fabric interactive-textile systems offer exciting new possibilities, provided that they exhibit sufficient robustness and autonomy to be reliably deployed in critical applications. Textile multiantenna systems, unobtrusively integrated in a professional garment, are key components of such systems, as they set up energy-efficient and stable wireless body-centric communication links. Yet, their functionality may be further extended by exploiting their surface as energy-harvesting platform. Different state-of-the-art energy harvesters are suitable for compact integration onto a textile antenna. We demonstrate this by integrating a power management system, together with multiple diverse scavenging transducers and a storage module, on a well-chosen textile antenna topology. We provide guidelines to ensure that the additional hardware does not affect the textile antenna's performance. Simultaneous scavenging from different energy sources significantly increases the autonomy of a wearable system, in the meanwhile reducing battery size.read more

Architectures for vibration-driven micropower generators
TL;DR: In this paper, the Coulomb-force parametric generator (CFPG) was proposed to operate in a resonant manner, and the sensitivity of each generator architecture to the source vibration frequency is analyzed and shown that the CFPG can be better suited than the resonant generators to applications where the source frequency is likely to vary.
