Abstract New types of metal–organic framework (MOF) materials have great potential in solving the current global dilemma on energy, environment, and medical care. Herein, based two kinds biomolecule‐MOFs (Bio‐MOFs) with favorable biocompatibility degradation‐reconstruction characteristics, we established a self‐powered muti‐functional device to achieve an efficient broad‐spectrum environmental energy collection biomedical applications. Combining Zn(II) carnosine‐based Zn‐Car_MOF possessing high piezoelectric response ( d 33 = 11.17 pm V −1 ) patterned polydimethylsiloxane (PDMS) film, tribo‐piezoelectric hybrid nanogenerator (TPHG) is constructed synergy output triboelectric effects. The Zn‐Car_TPHG demonstrates performance (131 at 100 kPa) wide range pressure (1 Pa–100 kPa), applications sensors. To expand application wearable device, conductive hexagonal prism MOF (Cu 3 (2,3,6,7,10,11‐hexahydroxytriphenylene) 2 (Cu‐HHTP)) synthesized employed load thymol (Thy). Cooperating Zn‐Car_TPHG, resulting Cu‐HHTP/Thy can ROS (singlet oxygen 1 O hydroxyl radical (·OH)) generation drug synergistic sterilization effect (efficiency ≥ 98%). In word, flexible Bio‐MOFs sustainable environmentally friendly, fields collection, biosensors, antibacterial.
