Polymer blend system has been commonly applied in a wide variety of applications. Herein, we propose to introduce sugar particles to polymer matrix, which results in a controllable polymer swelling under the action of osmotic pressure upon soaking in water. Taking advantage of this economic and environment-friendly, water-induced polymer swelling process, we have fabricated wrinkled conductive films and 3D structures by depositing conductive materials on the swollen polymer substrates for stretchable strain sensing devices. Several commercial silicone elastomers were utilized in the study. Key processing factors affecting the polymer swelling were investigated, including film thickness, sugar concentration, and temperature of…

As an engineering frontier, highly stretchable sensors are widely applied in many fields, such as human motion detection, personal healthcare monitoring, and human-machine interactions. In this study, novel silver nanowire (AgNW)-based stretchable sensors with hierarchical wrinkled structures were fabricated through a two-step process, namely water-induced swelling and AgNW deposition. As highly soluble additives, sodium chloride particles were incorporated into the elastomer matrix. Upon soaking in dopamine aqueous solution, significant swelling was introduced onto the elastomer substrate. The dopamine deposition is accompanied with the swelling process, which endows the sample surface with ultra-hydrophilicity. Additionally, the dopamine-modified swollen samples “capture” the nanowires…
