This research result is based on the application of a conductive film that has the same level of transparency as glass announced in 2021.This film is formed by a molecular precursor method that enables film formation at low cost and low energy, and exhibits high film uniformity in addition to high transparency and low refractive index.Therefore, light interference is low and visibility is high.In addition, since the material is glass, it exhibits high surface hardness (9H or more).

　Security camera lenses used in cold environments require countermeasures against condensation and snow accumulation in order to ensure a clear field of view. High transmittance and low refractive index make it ideal for applications in optical equipment.It can also be used for road signs and traffic lights, and can be expected to maintain high visibility by alleviating fogging, condensation, and freezing.We are currently looking for a company that can cooperate with social implementation.

　At the "University Trade Fair 2023", we will exhibit the actual product and explain in detail the principle and characteristics of the molecular precursor method, the flow up to the formation of the transparent film heater, and its heat generation characteristics.
