Processing and development of ferroelectric Bi(Fe2/3V1/3)O3-based electronic material for temperature sensor

Abstract

As temperature sensors, ferroelectric materials offer a wide range of fascinating applications. However, toxicity, hysteresis, low sensitivity, delayed response times, and recovery times are some of the inevitable drawbacks that prevent their use in a number of exciting and novel applications. The current study investigates a lead-free mixed oxide [Bi(Fe_2/3V_1/3)O₃: BFV] ferroelectric nanocomposite-based capacitive component which is supported by the studied dielectric, impedance, capacitive, and pyro-electric characteristics. It is a potential candidate for designing and developing a capacitive-type temperature sensor. In comparison to a standard capacitive temperature sensor, the fabricated BFV-nanocomposite-based sensor exhibits a reversible response with no noticeable fluctuation, good linearity (R² = 0.98), a quick response time (3.24 s), a recovery time (5.29 s), exceptional repeatability over several cycles, and a reasonably high sensitivity (639 fF/°C). For thirty days, long-term stability was ensured by monitoring the sensor’s response. The developed BFV nanocomposite sensor’s superior sensing response makes it a viable option for use in cutting-edge advanced electronics and industrial applications.
