Energy consumption levels show a never-ending increase since the industrial era. Toward sustainability objectives, it is of outstanding importance to reduce the amount of wasted energy, that typically comes as waste heat, as a consequence of nonunitary efficiency of any thermodynamic process. Herein, a breakthrough in conversion of low enthalpy heat into electricity is presented, based on a liquid state device that operates through multiphysics effects: thermomagnetic advection, triboelectricity, pyroelectricity, and Ludwig–Sorét effect. A synergistic interaction between ferroelectric surfaces and a complex composition colloidal suspension is evidenced, owing to an enhancement of the generated potential of 365% in comparison with pyroelectric effect and 267% in comparison with triboelectric effect, while the current extracted is 54% higher than the pyroelectric effect only and the power extracted by induction remains substantially unperturbed. The impact of this technology on society is also analyzed, on the basis of a set of practical applications, by means of a computational analysis.

支持多物理场的液态热收集：热释电和摩擦起电之间的协同效应

自工业时代以来，能源消耗水平呈现出永无止境的增长。为了实现可持续发展目标，减少浪费的能源量非常重要，这些能源通常以废热形式出现，这是任何热力学过程的非单一效率的结果。在此，基于通过多物理场效应运行的液态设备，提出了将低焓热转化为电能的突破：热磁平流、摩擦电、热电和路德维希 - 索雷效应。由于与热电效应相比产生的电位提高了 365%，与摩擦电效应相比，产生的电位提高了 267%，证明了铁电表面和复杂组成的胶体悬浮液之间的协同相互作用，虽然提取的电流仅比热释电效应高 54%，并且通过感应提取的功率仍然基本不受干扰。在一组实际应用的基础上，还通过计算分析来分析该技术对社会的影响。
