 The author analyzes the conceptions of ontological nihilism in the works of S. Kierkegaard, F. Nietzsche, M. Heidegger, E. Jünger. On the basis of this analysis, violence is defined as a manifestation of nihilism, of the “will to nothingness” and hypertrophy of the self-will of man. The article demonstrates the importance of the problem of nihilism. The nihilistic thinking of modern man is expressed in the attitude toward a radical transformation of the world from the position of his “absolute” righteousness. The paradox of the current situation is that there is the reverse side of this transformative activity, when there is only the appearance of action and the dilution of responsibility. Confidence in the rightness of own views and beliefs increases the risk of the violent imposition of own vision of reality. Historical and philosophical reconstruction of the conceptions of nihilism allowed to reveal the following projects of its comprehension and resolution: (1) the project of “positing of values,” which consists in the transformation of the evaluation, which is understood as another perspective of positing values, leading to the affirmation of being; (2) the project of overcoming nihilism from the space of temporality, carried out through the resoluteness to accept the historicity of own existence; (3) the project of overcoming nihilism as the oblivion of being from the spatial perspective of the “line,” allowing to realize the “glimpse” of being. The author concludes that it is impossible to solve the problem of violence and its various forms of its manifestation without overcoming “ontological nihilism.” Significant role in solving the problem of ontological violence is assigned to philosophy as a critical and responsible form of thinking, which is capable to help a person to bear the burden of the world, to provide meanings and affirm being, as well as to unite people and resist the fundamentalist claims of exclusivity and rightness.

The concept of energy harvesting works towards developing self-powered devices that do not require replaceable power supplies. Energy scavenging devices are designed to capture the ambient energy surrounding the electronics and convert it into usable electrical energy. A number of sources of harvestable ambient energy exist, including waste heat, vibration, electromagnetic waves, wind, flowing water, and solar energy. While each of these sources of energy can be effectively used to power remote sensors, the structural and biological communities have placed an emphasis on scavenging vibrational energy with ferroelectric materials. Ferroelectric materials have a crystalline structure that provide a unique ability to convert an applied electrical potential into a mechanical strain or vice versa. Based on the properties of the material, this paper investigates the technique of power harvesting and storage.
