By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-Current study results on robotics have been published. According to news originating from Beijing, People's Republic o f China, by NewsRx correspondents, research stated, "Multifunctional sensors hav e played a crucial role in constructing high-integration electronic networks." Financial supporters for this research include National Natural Science Foundati on of China. The news reporters obtained a quote from the research from Beihang University: " Most of the current multifunctional sensors rely on multiple materials to simult aneously detect different physical stimuli. Here, we demonstrate the large piezo -pyroelectric effect in ferroelectric Pb(Mg [ [1/3] ] Nb [ [2/3] ] )O [ [3] ] -PbTiO [ [3] ] (PMN-PT) single crystals for simultan eous pressure and temperature sensing. The outstanding piezoelectric and pyroele ctric properties of PMN-PT result in rapid response speed and high sensitivity, with values of 46 ms and 28.4 nA kPa-1 for pressure sensing, and 1.98 s and 94.66 nC °C-1 for temperature detection, respectively. By leveraging the distinct differences in the response speed of piezoelectric and pyroelectric responses, the piezo-py roelectric effect of PMN-PT can effectively detect pressure and temperature from mixed-force thermal stimuli, which enables a robotic hand for stimuli classific ation."
