1. An ion thermoelectric elastomer comprising:
a polymer matrix in which poly(ethylene glycol) diacrylate (PEGDA) and 2-hydroxyethyl acrylate (2-HEA) are cross-linked; and
an ion conductive dopant dispersed in the polymer matrix,
wherein the ion conductive dopant is hydrogen-bonded to the polymer matrix, and
wherein as a content of the ion conductive dopant increases, a Young's modulus of the ion thermoelectric elastomer decreases,
wherein a content of the 2-HEA is 55 wt % to 65 wt % based on a total of 100 wt % of the polymer matrix,
wherein the ion conductive dopant is included in an amount of 25 parts by weight to 35 parts by weight based on a total of 100 parts by weight of the polymer matrix,
wherein the ion conductive dopant is 1-Ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([EMIM] [TFSI]), and
wherein a Seebeck coefficient of the ion thermoelectric elastomer at a tensile strain of 250% is not lower than 20 mV K-1.
