Classification: CPC H  Y | IPC H

Claim 12:
13. The energy harvesting device of claim 1, wherein
when the following conditions 1, 2, and 3 are satisfied, an ohmic conductance between the first region and the second region satisfies Equation 1:
Condition 1: The first region and the second region have the same alkali ion concentration,
Condition 2: A length of the third region in a direction from the first region to the second region is 0.5 mm to 10 mm,
Condition 3: A voltage sweep range is −0.3V to +0.3V,

1.3≤GNa/GK  (Equation 1)

wherein GNa is a conductance (μS) when the alkali ion is Na+, and GK is a conductance (μS) when the alkali ion is K+.
