“…As revealed by the UV–vis spectra, the BMI in DMSO and PAAm organogel both show two strong absorption peaks at 376 and 530 nm at 1.5–2.0 V, resulting in the red color of the PAAm organogel observed. In addition, it is worth to point out that, although the dimethyl ferrocene in DMSO solution does not show any absorption peaks (Figure S6B), the BMI with dimethyl ferrocene exhibits higher absorption peaks and lower color change potential than those of BMI only, which attributes to the electrode activation function of dimethyl ferrocene …”

“…In addition, it is worth to point out that, although the dimethyl ferrocene in DMSO solution does not show any absorption peaks (Figure S6B), the BMI with dimethyl ferrocene exhibits higher absorption peaks and lower color change potential than those of BMI only, which attributes to the electrode activation function of dimethyl ferrocene. 47 To elucidate the electrochromic mechanism, the cyclic voltammetry (CV) of the PAAm organogel with or without BMI is analyzed. As shown in Figure 3B, two peak potentials of 1.2 and 1.6 V are observed for the PAAm organogel with BMI, which agrees well with the CV of BMI in DMSO solution (Figure S7).…”

“…This is related to the thickness and BMI concentration reduction caused by stretching. 47 Actually, the electrochromic effect of the PAAm organogel is also correlated with the BMI concentration. As shown in Figure S10, the PAAm organogel with 0.6, 1.25, and 2.5 mg/ mL MBI exhibits the color of pink, red, and crimson, respectively, with the applied potential of 2 V. Obviously, the PAAm organogel with a high concentration of BMI exhibits a more distinct electrochromic effect.…”

“…As shown in Figure S9, when the PAAm organogel is stretched around 100%, it exhibits a lighter color compared to its original status. This is related to the thickness and BMI concentration reduction caused by stretching …”

Inspired by chameleons’ structural color regulation capability, a simple, but effective, swelling method is proposed for the first time to prepare an ionic polyacrylamide (PAAm) organogel for simultaneous tactile sensing and interactive color changing. The PAAm organogel obtained by swelling the PAAm scaffold in the dimethyl sulfoxide solution of organic electrochromic material (OECM) shows an extremely large stretchability with an elongation of 1600%, a supersoftness with a compressive modulus of 7.2 kPa, an excellent transmittance up to 90%, and a very fast response time of 0.5 s combined with the characteristic of interactive color changing. The PAAm organogel also suggests a universal design ability to tailor coloration spectra for tactile sensors via simply changing the type and content of OECM. The tactile sensor based on a PAAm organogel is capable of serving as a wearable device for precisely tracing human body motion performance and directly visualizing the stress distribution via interactive color changing capability. It is demonstrated that the swelling method proposed here is a simple and practical strategy to prepare ionic organogels with both piezo-resistive and electrochromic effects.
