A Programmable Dual‐Regime Spray for Large‐Scale and Custom‐Designed Electronic Textiles (Adv. Mater. 9/2022)

Abstract

co-workers report how direct spray writing of functional nanomaterials into stretchy fabrics is enabled at sub-millimeter resolution to produce e-textiles with custom designs. The e-textiles fit well various body sizes and shapes of large animals under ambulatory conditions, allowing for high fidelity monitoring of health conditions from a distance.

Elastic Fibers/Fabrics for Wearables and Bioelectronics

“…[ 134 ] As shown in Figure 4d, silver nitrate (AgNO 3 ) nanoparticles seamlessly penetrated the fabric through atomized droplets under the action of two airflow modules at high and low speeds, allowing precise customization of the electrode pattern and fabric design while retaining the fabric's inherent comfort, breathability, and mechanical compliance. [ 135 ] The produced e‐textiles were evaluated for monitoring horses’ dynamic activity and physiological health indications, confirming the viability and universality of this process enhancement. This dual regime spraying effectively improves the applicability of inkjet printing to adapt complex textile substrates.…”
