Caption
a, A specific spike frequency is generated by the LIF neuron based on varying input spike frequencies from other neurons. The memcapacitor's electrical and optical programming enables the neuron to dynamically adjust its response characteristics. b, During the capacitance-time measurement on the MOSCap under varying light intensities at a wavelength of 465 nm, the capacitance values of the memcapacitor change significantly, achieving eight distinct levels. c, The results of the simulation show that the light-modulated memcapacitor exhibits adaptive behavior. When the device is illuminated at 465 nm with an intensity of 54.1 mWcm-2, the increased capacitance values lead to a reduction in output spikes. The higher capacitance slows down the charging and discharging times, resulting in fewer spikes overall. d, The transit method shows periodic fluctuations in a star's brightness due to an orbiting exoplanet passing in front of it. e, Dynamic illumination-sensing neurons in the SNN for exoplanet detection receive input signals from a target star's temporal light intensity variations. f, The testing accuracy over increased epochs reached 90%.
