Skin infections are major threats to human health, causing ∼500 incidences per 10 000 person-year. In patients with diabetes mellitus, particularly, skin often accompanied by a slow healing process, amputation, and even death. Timely diagnosis of infection strains on-site therapy vital in health safety. Herein, double-layered "test-to-treat" pad is developed for the visual monitoring selective treatment drug-sensitive (DS)/drug-resistant (DR) bacterial infections. The inner layer (using carrageenan hydrogel as scaffold) loaded bacteria indicators an acid-responsive drug (Fe-carbenicillin frameworks) detection DS inactivation. outer mechanoluminescence material (ML, CaZnOS:Mn2+) visible-light responsive photocatalyst (Pt@TiO2) incorporated elastic polydimethylsiloxane (PDMS). On basis colorimetric sensing result (yellow DS-bacterial red DR-bacterial infection), suitable antibacterial strategy guided then performed. Two available bactericidal routes provided double layers reflect advantage. controllable effective killing DR realized situ generated reactive oxygen species (ROSs) from combination Pt@TiO2 ML under mechanical force, avoiding physical light sources alleviating off-target side effects ROS biomedical therapy. As proof-of-concept, applied wearable wound dressing selectively dealing DS/DR vitro vivo. This multifunctional design effectively reduces antibiotic abuse accelerates healing, providing innovative promising Band-Aid point-of-care

Tactile sensing with stress and temperature as core elements have shown promising prospects in intelligent robots the human-machine interface. Mechanoluminescence (ML)-based can realize direct of mechanical stimulation, whereas indirect based on luminescent materials usually requires stimulation extra light or force. Herein, a trap-controlled material Sr2MgAl22O36:Mn2+ bifunctional mechano/thermal applications was developed investigated detail. Visualized bright green-emitting ML thermally stimulated luminescence (TSL) directly rapidly responded to dual Sr2MgAl22O36:Mn2+/PDMS composite film. It is worth mentioning that this study proposed new idea by initial intensity TSL due thermal-photo energy conversion, unlike previous sensor technology. Based this, we designed flexible optical skin simple structure verified its application prospect tactile response, establishing unique imaging mode providing convenient, reliable, sensitive way remotely visualize distribution temperature. This paves for development skins structures visibility robot sensing.
