Power generation humidity sensor has attracted attention in recent years due to its great potential in self-powered electronics. Herein, combining with the working mechanisms of primary battery and humidity sensor, we propose a facile primary battery-based device (PBD) with dual functions of humidity sensing and power generation, which is fabricated by copper adhesive tape (as pos. electrode), lithium chloride (LiCl) active layer (for adsorption and conduction), and aluminum adhesive tape (as neg. electrode) on the ceramic substrate. By regulating the concentration of the LiCl, 1.0 mol/L LiCl-based PBD can be developed as a humidity sensor, which exhibits a sensitivity of 4.86 mV/RH and good linearity in a wide detection range (10.9%-91.5% relative humidity) at room temperature (25°C). Moreover, 2.0 mol/L LiCl-based PBD can be developed as a power generator due to its high output of 0.55 V. Finally, multifunctional applications (such as respiratory monitoring, non-contact switch, lighting light-emitting diode (LED)) of the PBDs are demonstrated. This work not only provides a facile avenue to develop dual-function devices, but also exhibits a great potential in self-powered humidity sensors. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Reference of 7447-41-8).
Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Reference of 7447-41-8
