“…(12) and typical FPAA data, it can be seen that FPAA based circuits can be capable of capacitive sensing in the sub-pF range, but hardly below the hundred fF threshold. This is about one order of magnitude worse than the best ASIC interfaces [10,11] and more than an octave worse than the best interfaces built out of off-the-shelf parts [12,13], yet it is still suitable to a vast range of applications. Here, the distinct advantages of the FPAA approach can conversely represent a decisive point over ASICs and standard part circuits.…”

FPAAs have recently been introduced to reduce analog design costs and bridge the gap between ASICs and circuits made of standard-parts. Here, their applicability to capacitive sensing is investigated. Switched-mode FPAAs were not originally introduced for the readout of elementary sensors or their desensitization from parasitics. Nonetheless, we show that specific techniques can make them up to the task of reading capacitance variations in the tens fF range. We also show that FPAA sensor interfaces can achieve automatic, trimmer-free calibration by FPAA reconfiguration. We conclude by illustrating a sample application as a proof-of-concept of the proposed techniques.

“…Their work described four methods for producing the conductive tracks; weaving in a mix of conductive and insulating fibers, embroidering the circuit using conductive thread, textile electrodes separated by conducting strips (called bundle routing in the paper), and the use of conductive paint. A follow-up paper described a measurement system in combination with their E-textile that was capable of producing pressure images [88]. Other researchers also developed this type of technology.…”

Abstract:Textiles have been at the heart of human technological progress for thousands of years, with textile developments closely tied to key inventions that have shaped societies. The relatively recent invention of electronic textiles is set to push boundaries again and has already opened up the potential for garments relevant to defense, sports, medicine, and health monitoring. The aim of this review is to provide an overview of the key innovative pathways in the development of electronic textiles to date using sources available in the public domain regarding electronic textiles (E-textiles); this includes academic literature, commercialized products, and published patents. The literature shows that electronics can be integrated into textiles, where integration is achieved by either attaching the electronics onto the surface of a textile, electronics are added at the textile manufacturing stage, or electronics are incorporated at the yarn stage. Methods of integration can have an influence on the textiles properties such as the drapability of the textile.

“…Textile pressure fabric (e.g. in [5]) integrated in underwear or in a wheelchair, can prevent decubitus by detecting when the user has been seated in a certain position for too long. Radio Frequency Identification (RFID) is an all-encompassing term used for technologies that use radio waves to transmit.…”
