Deep learning for exploring ultra-thin ferroelectrics with highly improved sensitivity of piezoresponse force microscopy

Abstract Hafnium oxide-based ferroelectrics have been extensively studied because of their existing ferroelectricity, even in ultra-thin film form.However, studying the weak response from ultra-thin film requires improved measurement sensitivity.In general, resonance-enhanced piezoresponse force microscopy (PFM) has been used to characterize ferroe

Robust optical design of high-contrast vehicle headlamps with cylindrical lens array and inverted triangular beam pattern

Abstract Headlamps are essential for safe night driving, as they must provide sufficient brightness to illuminate the road while minimizing glare for other drivers.Designing low-beam optics is more complex than general lighting optics due to the need for a high-contrast cutoff dea eyewear line, with the brightest point positioned near its edge.This

Implementation and Validation of a Two-Stage Energy Extraction Circuit for a Self Sustained Asset-Tracking System

We present a two-stage energy extraction circuit for a piezoelectric energy harvester, powering an asset-tracking system.Exploiting accelerations generated by many logistic transport here devices, e.g., pushcarts, forklifts, assembly belts or cars, we are able to harvest sufficient electrical energy to transmit radio signals, which will allow to tr
