Abstract

This paper reports a conductive Velcro electrode with micro-cracks for the first time. The laser-induced micro-cracks increase the surface area of Velcro hooks and facilitate the adhesion of more silver particles. A cluster of Nylon-Ag hook are durable with repeated mechanical compression and multiple washing. After 100 times of compression, the plastic deformation is less than 23 μm (<10%). The impedance (@10 Hz) of the Velcro electrode is still 2.6% lower than the AgCl electrode after washing for 3 times. The resilient conductive hooks can effectively penetrate through thick hair for hi-fi bioelectric signal acquisition, compared with commercial AgCl electrodes.
