Sustainable development demands a process of unbroken improvement in using fewer numbers of resources for satisfaction of consumer needs. Sometimes, people harm the environment, although they try to treat it well. The imbalance in the moral environment caused by human perception and behavior is the major reason for unsustainable environment in today's era. To ensure sustainable development, various priority areas for action like energy and water conservation, pollution control, human health, waste management, biodiversity protection, ecosystem management, and most importantly, cognitive approach of humans have been illustrated. We also emphasize the pillars of sustainable environment, which includes environment protection as well as economic and social development. The chapter concludes considering a few measures to take for sustainable environment, including cognitive development in people, so that their approach must be environmentally friendly. Our main objective is to develop the technology with smart materials as cognitive outlook, remembering our holistic journey toward sustainable development.

Theoretical Modeling of Triboelectric Receiver transducer for Mechanic-Electrical Transformations

This paper theoretically and experimentally considers the pulsed mode of operation of the radiation-receiving system. The system contains two identical piezoceramic plates separated by a layer of immersion liquid (glycerin). The emitter was excited by the complex electrical signal of the special shape, which consisted of two half-cycles of the sine wave (exciting and compensating) on the natural frequency of the piezoplates. The forms of these signals were calculated by the authors and described in their previous papers using the d’Alembert method. The length of the electrical signal was estimated at the output of the piezoelectric receiver. The problem was solved theoretically using the finite element method. The acoustical system was simulated with the help of the COMSOL Multiphysics modeling environment. A comparative study of the theoretical and experimental results is carried out. The form of the signal at the output of the system was calculated by the d’Alembert method, and the simulated form by the finite element method was in good coincidence with the results of experimental and full-scale modeling. It is shown that the usage of complex waveforms allows achieving a significant pulse duration reduction of the electrical voltage at the output of the receiver.
