Abstract
Figure 1: A) HYFAR for haptic clothing interfaces. B) Uniaxial tensile test of HYFAR, its constitutive materials, and finite element (FE) simulation. C) Experimental data and simulation of the inflation of a circular actuator. D) Mapping of material parameter matrices to the FE mesh for an actuator embroidered with a cross-pattern (c.p.), and simulation results. E) Simulation ofHYFARwith various embroidered patterns inflated at 40 kPa. F) Blocked force versus bending angle for stadium-shaped HYFARs integrated in a unidirectional joint. Upper-body functional garments integrated with HYFAR G) (Design B) for kinesthetic haptic feedback, and with H) circular actuator (r = 4.5 cm; c.p. and four LEDs) for showcasing shape shifting behavior.
