Upper Limb Motor Function Rehabilitation System Leveraging Pressure‐Sensitive Intent Recognition
Advanced Science, EarlyView.A novel upper limb rehabilitation system for stroke patients combines liquid metal elastomer sensors with functional electrical stimulation (FES). By automatically adjusting stimulation intensity based on real‐time muscle force signals, the system enhances wrist movement capability (14° to 47° elevation) and aids neural recovery through heightened ...

Advanced Science, EarlyView.It is demonstrated that the kinetic rates and intrinsic nonradiative losses of purely organic emitters with thermally activated delayed fluorescence cannot be precisely determined by photoluminescent measurements alone. With device modeling, it is then possible to quantify the absolute nonradiative losses from singlets and triplets, and therefore the ...
