Smart and precise sensing is very important for the protection of both environment and personal security in modern civilized society. There are numerous sensing devices for detecting physical and chemical changes such as temperature, humidity, pressure, and chemical species. In this regard, conducting polymers is at the core of attention for the fabrication of next-generation sensor applications. Polypyrrole (PPy), is one of the emerging intelligent materials with a wide range of applications in the field of optical, electronic, and electrochromic devices and sensors. The stability in a different environment, ease of deposition from aqueous and non-aqueous media, adherence to diverse substrates, and high electrical conductivity made PPy a unique choice for sensor development. In recent years, PPy has proven an excellent candidate for sensing volatile organic compounds (VOCs) due to its selectivity and sensitivity towards target gas molecules, and detection of inorganic gases and VOCs. Consequently, to develop outstanding sensing devices attempts have been dedicated to developing PPy-based sensors for excellent mechanical and electrochemical performance. This review aims to provide a recent overview of progress in PPy-based advanced sensing devices. This review aims to provide a recent overview of progress in PPy-based advanced sensing devices. We have systematically discussed the challenges and future development of various sensing devices. Furthermore, the current understanding and performance evaluation of gas sensing mechanisms in PPy-based sensors are discussed theoretically and experimentally. We have also identified gaps in the state-of-the-art and hope that this study would lead to further research works into using PPy to make gas sensors. Finally, the future directions of various sensors with advanced PPy-based sensing systems have been prospected.

A PV-Biomass off-grid hybrid renewable energy system (HRES) for rural electrification: Design, optimization and techno-economic-environmental analysis

Smart cities provide critical infrastructure for a network of sensors, cameras, cables, wireless devices, and data centres that allow city authorities to deliver essential services more quickly and efficiently. Intelligent cities also make the use of sustainable construction materials and reduce energy consumption much more environmentally friendly. Practical usage of technology facilitates the construction of an effective transport management program, upgrades healthcare services, and establishes a broad contact network to interact with all businesses, workers, and other governmental interrelationships. The urbanization pattern is rising. Cities around the world face tight budgets and ageing facilities with further population shifts to metropolitan regions. Future communities need to be healthier, resilient, effective, relaxed, engaging, and intelligent. This chapter highlights the need for smart sensors in smart cities for remote control technologies. The smart temperature sensors are elaborated in detail. The applications of smart temperature sensors in smart cities also discussed with examples such as water management system, energy conservation, street lighting system and waste management.
