摘要: Abstract Metal oxide nano-structures on microhotplate platforms have attracted a great deal of interest in gas sensor research for their potential to create both highly responsive and extremely portable sensors. Much the current these sensors has focused upon creation hierarchical nanostructures, as van der Waals attraction between nanoparticles leads agglomeration that impair performance. In this article, ink-jet printing onto microhotplates was explored method avoiding nanoparticle produce an open film microstructure. Scanning electron microscopy used study deposited thin featuring microstructure free large agglomeration. Sensor response times printed SnO2 were found be comparable particle films when exposed methane carbon monoxide background dry air. Both microspheres had superior compared micron-size particles due increased surface area nano-structures. This implies proper control produces similar performance structures use reproducibly manufacturing high-performance
