Abstract Organic molecule–functionalized lead chromate nanoparticle was synthesized using a complexation strategy route. The structural characterization revealed the single-phase lead chromate system belongs to monazite-type monoclinic structure with the space group of P2 1 /n. The unit cell consists of an alternating chain of polyhedra (PbO 9 ) and tetrahedra (CrO 4 ) units, connected via edge and corner-sharing arrangement. A flexible device of lead chromate was fabricated and investigated dielectric capacitance, electrical impedance, conductivity, and field dependent polarization performances under different frequency and temperature environments. The device displayed a maximum dielectric constant ( ε ʹ) value ~ 2400 at 120°C under 100 Hz frequency condition. High dielectric constant value is originated from the orientation polarization of CrO 4 unit and space charge contribution in the system. AC conductivity of the device suggested the polaronic charge carriers control the overall conduction process via localized hopping mechanism. A fatigue-free polarization behavior was observed in the device under the applied field of 4.0 kV/mm, for 10 3 cycles and retained the polarization value ~ 0.26 μC/cm 2 over the switching cycles. Lead chromate–based device also showed pressure-induced voltage generation under different pressure conditions and could have the potential application as a voltage generator.

Abstract The detection of humidity is crucial for various applications in industry, healthcare, and the environment. To meet the needs of many of these applications, humidity sensors must be flexible, disposable, and easily fabricated. This article introduces a cost-effective and flexible humidity sensor created on a paper substrate, using graphene-polypyrrole-carbon black ink. The sensor shows excellent sensing capabilities, with a resistance change of approximately 12.2 Ω/%RH when exposed to humidity ranging from 23%RH to 92.7%RH. Additionally, the sensor is highly flexible, stable, and repeatable for over 50 cycles, with a short response/recovery time of approximately 5 s/7 s for respiration rate monitoring. Furthermore, the sensor demonstrates good reproducibility, with minor variations of approximately ± 1 Ω/%RH. The performance of the produced humidity sensor is assessed for monitoring humidity in a spatial setting as well as monitoring soil moisture. As a result, these findings indicate that the proposed humidity sensor is resilient enough to be used in wearable and flexible electronic devices.
