“…Pyroelectric materials allow direct conversion of thermal energy to electrical energy, based on time-temperature changes, and additionally, since all pyroelectrics are also piezoelectrics, they enable the conversion of mechanical to electrical energy. Recently, research activities on improving thermal energy harvesting performance by surface modification of pyroelectric materials using carbon-based coatings have been identified [ 126 , 127 , 128 , 129 ], some of them attempting surface modification of PZT and BT by graphene-based coatings. Liu et al [ 129 ] processed a thin, soft, piezoelectric composite of graphene, PZT and PDMS for a skin-integrated electronic device, capable of converting body mechanical activity into electricity.…”

Research activity on ceramic/graphene composites and hybrids has increased dramatically in the last decade. In this review, we provide an overview of recent contributions involving ceramics, graphene, and graphene-related materials (GRM, i.e., graphene oxide, reduced graphene oxide, and graphene nanoplatelets) with a primary focus on applications. We have adopted a broad scope of the term ceramics, therefore including some applications of GRM with certain metal oxides and cement-based matrices in the review. Applications of ceramic/graphene hybrids and composites cover many different areas, in particular, energy production and storage (batteries, supercapacitors, solar and fuel cells), energy harvesting, sensors and biosensors, electromagnetic interference shielding, biomaterials, thermal management (heat dissipation and heat conduction functions), engineering components, catalysts, etc. A section on ceramic/GRM composites processed by additive manufacturing methods is included due to their industrial potential and waste reduction capability. All these applications of ceramic/graphene composites and hybrids are listed and mentioned in the present review, ending with the authors’ outlook of those that seem most promising, based on the research efforts carried out in this field.

It is now well reported that the coatings of graphene/candle soot/black carbon can improve the performance of pyroelectric materials. Herein, the performance of candle soot‐coated pyroelectric material (piezoelectric buzzer) under solar heating is reported. To compare the performance, coated/uncoated piezoelectric buzzers are exposed to solar light as well as IR lamp separately. Piezoelectric buzzer shows multiple times superior performance after coating of candle soot. The open‐circuit voltage improves five times with a peak voltage of 3.31 V in solar light. The comparative enhancement in short‐circuit pyroelectric current is four times with a peak current of 2.73 μA. Also, the power and energy densities show multifold enhancement after coating.

This article reports the thermoelectric‐based solar energy harvesting. The effect of candle soot (CS) coating on solar energy harvesting potential of thermoelectric modules is studied. To compare the performance, uncoated/coated modules are exposed to solar radiations (through Fresnel lens) and the other side is kept at lower temperature using continuous water flow. Substantial enhancements in electrical outputs are observed due to CS coating on the upper surface of the thermoelectric module. The open‐circuit voltage and short‐circuit current across coated module improve more than six times in comparison to the uncoated module with maximum voltage and current reaching up to 1.5 V and 14 mA. Similarly, the generator can deliver a maximum power of 10 mW across a resistance of 50 Ω. Results indicate that the CS coating is an effective technique to improve the performance of thermoelectric materials for running sensors and other low‐power electronic devices.
