Abstract

In this study, we demonstrate the heat generation characteristics of microheaters prepared with an ITO nanoparticle (NP) paste, which is a mixture of ITO NPs, polymethyl methacrylate, and terpineol. A comparison with microheaters prepared with ITO NPs only shows that the organic additives substantially enhance their heat generation characteristics. The maximal temperature obtained is 445°C at a bias voltage of 12 V, which is three times higher than for the NP microheaters. Moreover, the NP-paste microheaters have better thermal stability and a more uniform heating zone. The enhancement in the heat generation characteristics results from the smoother surfaces and the higher density of the NP-paste films.
