This study proposes programmable ferroelectric bionic vision hardware emulating selective attention. Tunneling effects of photogenerated carriers are controlled by dynamically varying the energy barrier, modulating memory strength (9.1% to 47.1%) without a peripheral storage unit. Ferroelectric P(VDF-TrFE) allows a single device to have multiple nonvolatile states and implement selective attention. UV light information is selectively recorded and suppressed with high current decibel levels. Positive polarization shows high wavelength dependence in image attention processing, achieving 95.7% accuracy in multi-wavelength image classification. This work enriches neuromorphic functions of bioinspired sensors and advances bioinspired optoelectronics.
