Figure 1. Overview of the DTTS. (A) One example of the application of the sensor in monitoring the normal and pressure loads between the leg and RGO; (B) Exploded-view schematic of the sensor; (C) Photograph of the sensor: (left) orthogonal-view; (right) top-view; (D) Performance comparisons between inductive tactile sensors based on different mechanisms. The geometry of the sensors is kept the same. Schematics and mechanisms of different types of inductive sensors are provided in Supplementary Note 2 and Supplementary Figure 2. Detailed material and fabrication process can be found in the Experimental section. ΔLz represents inductance changes along the z-axis. L0 represents the initial inductance of the sensor. DTTS: Dual tri-axial tactile sensors; RGO: reciprocating gait orthosis; PDMS: polydimethylsiloxane.
