“…The conductive active material is usually an intrinsically conductive material (e.g., liquid metals, [ 3 ] hydrogel, [ 4 ] poly(3,4‐ethylenedioxythiophene) polystyrenesulfonate (PEDOT: PSS) [ 5 ] ) or formed by mixing conductive particles/wires (metals, [ 6 ] carbon‐based materials [ 7 ] ) with polymers. [ 8 ] Among them, metal‐based fillers as conductive agents have advantages owing to their excellent electrical conductivity and long‐term stability. [ 9 ] The stretchable substrate is generally composed of one or more elastomer layers, which form a bottom foil or fully encapsulated protector for the conductive active material.…”

“…[9] The stretchable substrate is generally composed of one or more elastomer layers, which form a bottom foil or fully encapsulated protector for the conductive active material. [10] Many researchers have developed a variety of stretchable devices by fabricating the conductive active material onto the elastomer substrate using lithography, [11] transfer technology, [8] or printing technology. [12] Therein, printing technology is an attractive way owing to its low fabrication cost and high production efficiency.…”

Printable and stretchable conductive elastomers have promising applications for epidermal and wearable electronics, soft robotics, etc. However, these conductive materials usually present poor performances in monitoring dynamic strains. The monitored signals are distorted and lose key physical signs, which limit their practical applications. Through investigating kinetic behaviors of conductive pathways along longitudinal and transverse directions in these conductive materials, the physical mechanism of signal distortion under dynamic strains is interpreted. To overcome this strain sensing problem, an Ag‐Ecoflex‐polydimethylsiloxane (PDMS) elastomer by printing Ag‐filler‐Ecoflex‐matrix ink on PDMS is proposed. Compared to other conductive materials, the Ag‐Ecoflex‐PDMS elastomer has preferable dynamic performances, embodying smaller overshoot response, higher strain sensitivity, and lower hysteresis. A deep‐learning‐based dynamic calibration method is proposed to successfully correct the sensing signals and eliminate the hysteresis error to 0.1%. Moreover, the proposed Ag‐Ecoflex‐PDMS elastomers gain high electrical conductivities owing to thermal expansion and contraction of PDMS substrate during the thermosetting of conductive ink, and thus can be both excellent stretchable sensors and stretchable conductors. Demonstrations of monitoring knee motion with high fidelity and human–robot collaborative playing ping‐pong validate superior accuracy and robustness of the Ag‐Ecoflex‐PDMS elastomers for monitoring human dynamic activities, human‐machine collaboration, virtual reality, etc.
