In this work, we employed liquid-phase exfoliation from naturally abundant biotite to demonstrate the synthesis and characterization of ultrathin metal oxide termed biotene. To gather energy, the flexoelectric response of the atomically thin biotene during sequential bending has been used. The effective flexoelectric response was improved due to the presence of surface charges, and the voltage increased up to 8 V, with a high mechano-sensitivity of 0.79 VN<sup>-1</sup> for force applied. The flexoelectric response was verified using density functional theory (DFT) simulations. In the atomically thin biotene, the magnetic field and thermal heating suggest increased sensitivity. The development of two-dimensional (2D) metal-oxide biotene for energy generation and harvesting indicates to a multitude of potential 2D-oxide materials for energy generation and harvesting.
