The ultrasensitive piezoelectric sensors with the capability of sound recognition have attracted extensive attention due to their unique characteristics. However, fabrication acoustic favorable flexibility and sensitivity via simple controllable methods remains a significant challenge. Herein, an adaptive sensor based on polyimide (PI) composite foams containing fluorine groups is developed. uniform porous morphology endows foam-based remarkable 0.9536 V/N over broad pressure range (2.5–12.5 N), rapid response recovery times (18 15 ms, respectively), outstanding durability (over 19,000 cycles). Moreover, are capable effectively monitoring human motions, generated output voltages reached ∼30 V for practical applications as intelligent household devices. In particular, exhibit excellent detecting wide sounds, indicating exceptional sensitivity. This work offers promising opportunities design development high-performance recognition, motion monitoring, self-powered wearable devices in extreme environments.

Polyimide (PI) aerogel with high thermal stability and low conductivity exhibits significant application value in the aerospace field. Nevertheless, traditional preparation methods of PI face challenges a complicated manufacturing process mechanical strength, which severely restrict their industrial scalability. Herein, series aerogels stable topological porous hierarchy were designed fabricated through synergistic chemical imidization salt template strategies. This is composed micropores sizes 5–15 μm macropores 200 μm–1000 μm, respectively. The show lightweight (0.03–0.06 g/cm3), exceptional flame-retardant properties. In particular, ultralow 0.028 W/(m·K), demonstrating outstanding insulation characteristics. Moreover, conductive PI@PPy composite by depositing pyrrole (PPy) within matrix aerogels, potential applications as flexible piezoresistive sensors photothermal conversion devices investigated. prepared demonstrate great fields microelectronics.
