“…This voltage is well within the range of what is used by modern energy harvesters to power small electronics. [27,28] The proposed hygroscopic generator does not replace kinetic energy harvesters but presents an alternative to utilize, on its own or in combination with other types of energy harvesters, environmental changes associated with natural systems. An example application would be an energy harvest from moisture changes during breathing or ventilation, [29] a task that would otherwise require obstructing normal airflow with a kinetic energy harvester.…”

Passive actuation is the production of movement or deformation without external power sources or control systems. This phenomenon has been gaining significant attention in the engineering community due to its potential use in energy‐efficient systems, in which part of the functionality is programmed in the material composition to reduce overall cost and complexity. Biological organisms, formed through millennia of evolution in a paradigm of limited resources and energy and at a multiscale equilibrium with their environment, have developed a myriad of outstanding materials and strategies for integrating complex functionalities into their multiscale structural design. In this study, the arthropod exoskeleton's chitinous composition and manufacturing strategies are used to reproduce its complex relations with external forces and water‐driven molecular rearrangement and use them to produce electricity and actuate a mechanical hand. The proposed technology is unique in combining the generation of strong forces and the integration of the principles and materials of biological organisms, leading to significant advances in the design and performance of passive solutions integrated into biological systems for a wide range of applications, such as biorobotics, medical devices, and energy harvesting.

The optimization of power for sustainable resources become very crucial factor now a days due to increase the demand of energy. This paper presents the PZT tile power optimization with respect to subject weight and sensor quantity and mechanical and electrical characteristic of sensor. The most efficient combination of components and levels is thus predicted, and the results are analysed using ANOVA and Taguchi’s statistical optimization technique. The analysis predicts that the PZT Tile produced more output for the rigidity 44.97%, subject weight 30.09%, frequency contribution 12.39%, and sensor number 3.35%. The contribution of weight and rigidity influence the output responses. It also provides descriptions of the other combination of parameters that are feasible. In this study, R-sq. is discovered to be larger than 90%, i.e., 91.185% for voltage; hence, the model is suitable. Finally, the Taguchi optimization method can be utilised to forecast the ideal power incorporation factor to maximize the power according to the application of PZT walking tile.

“…Energy-harvesting technology that derives energy from the surrounding environment, such as from solar radiation [1], pressure [2,3], friction [4], radio frequency (RF) energy [5,6], vibration [1,7], temperature [1,8], and light [9], is one of the core technologies of Internet-of-Things (IoT) sensors that operate without the need for power or batteries [10][11][12][13]. Since the power available for energy harvesting is quite limited, power consumption of less than a few microwatts is required in energy-harvesting circuits [14,15].…”

An ultralow-power ultrawideband (UWB) transmitter with an energy-efficient injection-locked radio frequency (RF) clock harvester that generates a carrier from an RF signal is proposed for RF energy-harvesting Internet-of-Things (IoT) sensor applications. The energy-efficient RF clock harvester based on the injection-locked ring oscillator (ILRO) is proposed to achieve optimal locking range and minimum input sensitivity to obtain an injection-locked 450 MHz clock in ultralow-power operation. A current-starved inverter-based delay stage is adopted that allows delay adjustment by bias voltage to minimize dynamic current consumption while maintaining a constant delay regardless of changes in process, supply voltage, and temperature (PVT). To minimize static current consumption, a UWB transmitter based on a digital-based UWB pulse generator and a pulse-driven switching drive amplifier is proposed. The proposed injection-locked RF clock harvester achieves the best RF input sensitivity of −34 dBm at a power consumption of 2.03 μW, enabling energy-efficient clock harvesting from low RF input power. In ultralow-power operation, a 23.8% locking range is achieved at the RF injection power of –15 dBm to cope with frequency changes due to PVT variations. The proposed UWB transmitter with RF clock harvester achieves the lowest energy consumption per pulse with an average power consumption of 97.03 μW and an energy consumption of 19.41 pJ/pulse, enabling operation with the energy available in RF energy-harvesting applications.
