- A suspended 1D nano-heater capable of heating immediately to 250 °C within a low power of 1.6 mW is presented; this is facilitated at a wafer level without any nano-scale alignment process owing to the suspended 1D architecture and built-in shadow mask. This 1D nano-heater is applied to gas sensors through the localization of functional MOS nanomaterials, enabling reliable and sensitive gas detection.

- Homojunction refers to a bonding of the same type of semiconductor material, and an energy barrier formed between the two greatly improves the sensitivity of the gas sensor. Unlike the existing methods, a technology for significantly improving gas accessibility by surrounding a carbon mesh, which is a suspended skeleton structure, in a radial form of a sensing material has been developed. Moreover, sensitivity, minimum measurement concentration (LOD), and stability were greatly improved when such a junction structure is manufactured in an array form.
