Description
Dongze Yan, Li-Hua Shao, Huiling Duan, and Wanlin Guo turn squeezing into electricity with a soft composite laced with carbon nanotubes. Ion transport powers many biological and electrochemical systems, but conversion efficiency has a stubborn ceiling. Bending the porous silicone composite creates flexoelectric fields that drive ions, and the two effects reinforce each other. Total mechanical to electrical conversion hit 6.54%, and net efficiency reached 28.81% on the stricter accounting.
Current per unit mass rose a million-fold against a solid reference form. One squeeze of 1.02 grams lit 800 light-emitting diodes, and output stayed stable over ten million cycles. The team pitches cheap, compliant harvesters for sensing and biosignaling.
