Flexibility is a key parameter of device mechanical robustness. The most profound challenge for the realization of flexible electronics is associated with the relatively low flexibility of power sources. In this article, two kinds of energy applications, which have gained increasing attention in the field of flexibility in recent years, are introduced: the lithium-ion
The energy used in post-prandial state during rest and physical activity is derived predominantly from the oxidation of carbohydrate (CHO) and fat. Although protein can also serve as a source of energy, amino acids oxidation is usually tightly adjusted to amino acids intake and their contribution to total energy expenditure is rather insignificant in healthy subjects.

Energy storage efficiency depends on carbon electrode properties in batteries and supercapacitors. Active carbons ideal due to availability, low cost, inertness, conductivity.
Fat is the body''s most concentrated source of energy, providing more than twice as much potential energy as carbohydrate or protein (9 calories per gram versus 4 calories each per gram). During exercise, stored fat in the body (in the form of triglycerides in adipose or fat tissue) is broken down into fatty acids.

$begingroup$ I think this answer mixes up the advantage of phosphates as energy carriers with the predominance of ATP. The case for phosphates is nicely made by Westheimer''s 1987 paper; but there is little reason to suppose that ATP is chemically special compared to, say, GTP --- the prevalence of ATP over other triphosphates is likely just an
Energy storage and conversion are vital for addressing global energy challenges, particularly the demand for clean and sustainable energy. Functional organic materials are gaining interest as
It indicated that the synergistic effect of different metal ligands has a certain impact on electrochemical energy storage performance, which provided an example for the design of 2D MOFs with adjustable structure in the future and laid a foundation for the realization of more efficient energy storage research.
Because the mechanical efficiency during exercise is ~20%, most of the energy generated from metabolism is released as heat, which is dissipated by the evaporation of sweat and other heat-loss
In summary, the integration of energy storage and conversion capabilities in functional organic materials represents a paradigm shift toward more efficient, cost-effective, and versatile energy devices.

There is enormous interest in the use of graphene-based materials for energy storage. Graphene-based materials have great potential for application in supercapacitors owing to their unique two-dimensional structure and inherent physical properties, such as excellent electrical conductivity and large specific surface area.
All energy transfers and transformations are never completely efficient. In every energy transfer, some amount of energy is lost in a form that is unusable. In most cases, this form is heat energy. Thermodynamically, heat energy is defined as
All energy transfers and transformations are never completely efficient. In every energy transfer, some amount of energy is lost in a form that is unusable. In most cases, this form is heat energy. Thermodynamically, heat energy is defined as the energy transferred from one system to another that is not work.
