Bio-Inspired Highly Flexible Dual-Mode Electronic Cilia


Inspired by biological cilia, a highly flexible dual-mode electronic cilia (EC) is fabricated from graphene-coated magnetic cilia arrays. Polydimethylsiloxane is used as the matrix to make the artificial cilia flexible while Co particles are used to endow the cilia magnetic and graphene coating is employed to make the cilia conductive. The EC-based sensor shows a high sensitivity of 0.4% Pa-1 for pressure from 0­100 Pa and a low detection limit of 0.9 Pa. The responsive behavior of the EC-based sensor is highly stable in a wide frequency range of 0.1-10 Hz up to 10000 cycles. Meanwhile, the magnetic field sensitivity of the EC sensor is around 12.08 T-1 for magnetic field intensity from 150 to 160 mT. Consequently, the EC sensor is successfully applied in blood pulse monitoring, pressure and magnetic field switching, visualized pressure and magnetic field detection. Due to its high sensitivity, high durability and dual-mode responsiveness, the flexible EC sensor goes far beyond the capability of human skin, which is believed to have a great potential in healthcare, robotics, e-skin and smart surgical tools, etc.
