A non-printed integrated-circuit textile for wireless theranostics

Abstract

While the printed circuit board (PCB) has been widely considered as the building block of integrated electronics, the world is switching to pursue new ways of merging integrated electronic circuits with textiles to create flexible and wearable devices. Herein, as an alternative for PCB, we described a non-printed integrated-circuit textile (NIT) for biomedical and theranostic application via a weaving method. All the devices are built as fibers or interlaced nodes and woven into a deformable textile integrated circuit. Built on an electrochemical gating principle, the fiber-woven-type transistors exhibit superior bending or stretching robustness, and were woven as a textile logical computing module to distinguish different emergencies. A fiber-type sweat sensor was woven with strain and light sensors fibers for simultaneously monitoring body health and the environment. With a photo-rechargeable energy textile based on a detailed power consumption analysis, the woven circuit textile is completely self-powered and capable of both wireless biomedical monitoring and early warning. The NIT could be used as a 24/7 private AI “nurse” for routine healthcare, diabetes monitoring, or emergencies such as hypoglycemia, metabolic alkalosis, and even COVID-19 patient care, a potential future on-body AI hardware and possibly a forerunner to fabric-like computers.

Challenges and emerging opportunities in transistor-based ultrathin electronics: design and fabrication for healthcare applications

“…In addition to the textile of solar cells, triboelectric yarns have been gradually explored recently. 70,236,237 Although the assembly of all e-textile systems, containing power sources and displays, is still poorly understood, pioneer reports have already demonstrated e-textile systems 56,216 (Fig. 10J and K).…”

“…Examples include photovoltaic cells, batteries, wire-type infrared emission modules, transistors as active components, tensile stress sensors, pH sensors, and optical sensors within non-printed wire- and fabric-types. 216 The principle of this research could serve as a general design for application in a wider range of wearable devices.…”

“…In comparison to 2D devices based on paper and textiles, 1D SABs should be more attractive owing to their excellent compatibility with textile electronics and implantable medical devices. [ 27 , 28 , 29 , 30 ] However, to the best of our knowledge, no studies have been conducted concerning wearable, weavable, and scalable 1D SABs.…”
