Recent growing pursuit of skin-mountable devices has been impeded by the complicated structures most sensing systems, containing electrode grids, stacked multilayers, and even external power sources. Here, a type touch sensing, termed "triboresistive sensing", is introduced for gridless recognition based on monolayered ionic generators. A homogeneous monolayer, i.e., poly(dimethylsiloxane) (PDMS), generates electricity electric field generated touch. Voltages at each corner PDMS rely...
Abstract Thermo‐responsive hydrogels can generate the actuation force through volumetric transitions in response to temperature changes. However, their weak mechanical properties and fragile performance limit robust applications. Existing approaches enhance these have typically depended on additional components, leading an unavoidable interference performance. In this work, thermo‐responsive are fabricated solvent engineering. A particular solvent, N ‐methylformamide, interacts affinitively...
Structure changes mediated by anisotropic volume of stimuli-responsive hydrogels are useful for many research fields, yet relatively simple structured objects mostly used due to limitation in fabrication methods. To fabricate complex 3 dimensional (3D) structures that undergo structure response external stimuli, jammed microgel-based inks containing precursors developed extrusion-based 3D printing. Specifically, the prepared absorbing poly(acrylic acid) or poly(N-isopropylacrylamide)...
In this work, we describe the development of an implantable ionic device that can deliver a spatially targeted light source to tumor tissues in controllable manner. The motivation behind our approach is overcome certain limitations conventional approaches where delivered from outside body and only achieves low penetration depths. Also, avoid issues come periodic need replace device's battery, utilize wireless power transfer system synchronized with operation structure. testing implanted,...
Unlike pigment-based colors, which are determined by their molecular structure, diverse colors can be expressed a regular arrangement of nanomaterials. However, existing techniques for constructing such nanostructures have struggled to combine high precision and speed, resulting in narrow gamut, prolonged color fabrication time. Here, this work reports phototunable mono ink that generate wide range controlling regularly arranged nanostructure. Core-shell growth controlled polymerization time...
Triboresistive Touch Sensing In article number 2108586, Jeong-Yun Sun and co-workers report a novel type of touch sensing, termed triboresistive which is developed for self-powered gridless recognition. An ionic poly(dimethylsiloxane) exhibiting high transmittance (96.5%), stretchability (539.1%), resilience (99.0%), conductivity (0.25 mS m−1) designed to generate power based on the electric field generated by touch. The voltages ensure recognition positions without electrode grid layers...
