Flexible iontronic pressure sensors have attracted extensive attention in intelligent robots and wearable healthcare devices for their flexible properties sensing functions. Introducing surface microstructures has remarkably enhanced sensitivity, whereas achieving with high sensitivity over a broad linear range remains challenging. Here, we propose hierarchical synergetic strategy by combining hemisphere porous microstructure, realizing (9.27 kPa-1), fast response speed (<15 ms), (R2 = 0.998) (10 Pa-400 kPa). The linearity of the sensor is attributed to hemispherical which improves compressibility compensates effect structural stiffening. excellent application potential our monitoring spatial distribution demonstrated. microstructure provides general expected be applied other types calling both linearity.
