Aqara makes more smart sensors than almost anyone else, and I find them to be consistent and stable. Here are the presence ...

Here we report on a bioresorbable fluorescence sensor for in vivo pH monitoring. The sensor leverages a nanometer-thick multilayer stack of polyelectrolytes labelled with a pH-insensitive fluorophore ...

A photonic crystal fiber (PCF)-model interferometer (MI)-based relative humidity (RH) sensor is proposed and experimentally demonstrated. The PCF-MI is formed by fusion splicing a short length of PCF ...
