The ultimate or end point of functional materials development is the realization of strong coupling between all energy regimes (optical, electronic, magnetic, and elastic), enabling the same material to be utilized for multifunctionalities. However, the integration of multifunctionalities in soft materials with the existence of various coupling is still in its early stage. Here, the coupling between ferroelectricity and charge transfer by combining bis(ethylenedithio)tetrathiafulvalene‐C60 charge‐transfer crystals with ferroelectric polyvinylidene fluoride polymer matrix is reported, which enables external stimuli‐controlled polarization, optoelectronic and magnetic field sensing properties. Such flexible composite films also display a superior strain‐dependent capacitance and resistance change with a giant piezoresistance coefficient of 7.89 × 10 −6 Pa −1 . This mutual coupled material with the realization of enhanced couplings across these energy domains opens up the potential for multisensing applications.
