| 研究開始時の研究の概要 |
Several energy harvesting systems have been developed to collect energy from ambient energy sources, such as sunlight, vibration and heat.These systems pose advantages and disadvantages. Herein, a novel concept of a combination between fluidic transport in nanochannels and thermal charging of metal oxide material is proposed which expect to generate a higher output voltage as well as the electrical power.

| 研究実績の概要 |
This work demonstrates thermal-to-electric energy conversion based on ionic nanofluidic transport in nanochannels inducted by a temperature gradient. Two types of highly periodic and high aspect ratio nanochannels have been fabricated in a silicon (Si) substrate and in an aluminium oxide (Al2O3) membrane. Silicon nanochannels with diameter of 100 nm and height of 300 μm have been produced by metal-assisted chemical etching process (MACE), while nanochannels with the dimensions of the 10 nm and 3 μm respectively, were fabricated in a Al2O3 membrane by the anodic aluminum oxidation (AAO) process. Moreover, a novel approach of thermally nanofluidic energy harvesting was proposed and conducted.
