Photographs of the coated ICs on Fabric (A). (a) Acrylic; larger acrylic lump on the backside is visible as a white fabric, indicated with an arrow. This hard piece of acrylic makes the t-matching section hard, which possibly prevented it from breaking in laundry. (b) Silicone. (c) Epoxy. (d) PVA2 glue (PVA1 glue looks similar). (e) Latex glue.
