Abstract Nowadays the development of machine vision is oriented toward real-time applications such as autonomous driving. This demands a hardware solution with low latency, high energy efficiency, and good reliability. Here, we demonstrate robust self-powered in-sensor computing paradigm ferroelectric photosensor network (FE-PS-NET). The FE-PS-NET, constituted by photosensors (FE-PSs) tunable photoresponsivities, capable simultaneously capturing processing images. In each FE-PS, photovoltaic...
In-sensor computing has emerged as an ultrafast and low-power technique for next-generation machine vision. However, in situ training of in-sensor systems remains challenging due to the demands both high-performance devices efficient programming schemes. Here, we experimentally demonstrate artificial neural network (ANN) based on ferroelectric photosensors (FE-PSs).

Second-order memristors are considered as ideal synaptic emulators for their capability of exhibiting ${\mathrm{Ca}}^{2+}$-like dynamics. Recently, ferroelectric second-order were developed, but whether temporal conductance evolution is related to polarization dynamics remains unclear owing the difficulty in directly measuring these devices. This issue addressed here by using a diode (FD) that shows both memristive behavior and well-shaped polarization-voltage hysteresis loops. It...
Several new p-type semiconducting materials with lower electron-donating ability than the parent sexithiophene were synthesized and their thermal, morphological, FET properties investigated. The incorporation of thiazole rings into oligothiophenes was designed to highest occupied molecular orbital (HOMO) level molecules hence make them less susceptible p-doping. devices based on a dihexylated six-ring compound thiazoles as central indeed showed enhanced stability p-doping over those typical...
