Abstract Multimodal tactile sensors, as key information input channel in human‐machine interactions, have faced the significant challenges including high power‐consumption, multimodal data fusion, and wireless transmission. In this work, a battery‐free sensor (TC‐MWTS) based on tribo‐capacitive coupled effect for normal shear force fusion sensing is proposed, which enabled by 3D structure combining triboelectric capacitive with an inductive coil. A equipped contact‐discharge structures exhibits 25‐fold signal enhancement compared to conventional sensors. Based characteristics of dual time‐frequency domain existing signals, both forces can simultaneously be converted into voltage amplitude V eigenfrequency f , respectively, without crosstalk complex decoupling signals. The TC‐MWTS maximum sensitivity 2.47 kPa −1 from 2 30 0.28 MHz N between 0.3 1.0 N. Finally, excellent capability sense multidimensional interaction demonstrated. This work innovatively proposes new mechanism methodology effectively fusing processing information, may drive tremendous development low‐power system.
