Touchless technology has garnered significant interest in recent years because of its effectiveness in combating infectious diseases such as the novel coronavirus (COVID-19). The goal of this study was to develop an inexpensive and high-precision touchless technology. A base substrate was coated with a luminescent material that emitted static-electricity-induced luminescence (SEL), and it was applied at high voltage. An inexpensive web camera was used to verify the relationship between the non-contact distance to a needle and the applied-voltage-triggered luminescence. The SEL was emitted at 20-200 mm from the luminescent device upon voltage application, and the web camera detected the SEL position with an accuracy of less than 1 mm. We used this developed touchless technology to demonstrate a highly accurate real-time detection of the position of a human finger based on SEL.
近年来，由于其在防治新型冠状病毒（COVID-19）等传染病方面的有效性，非接触式技术引起了广泛关注。本研究的目的是开发一种廉价且高精度的非接触式技术。基底涂覆有发射静电诱导发光（SEL）的发光材料，并施加高压。使用廉价的网络摄像头验证了距针的非接触距离与施加电压触发的发光之间的关系。SEL 在施加电压后从发光装置发出，距离为 20-200 毫米，网络摄像头以小于 1 毫米的精度检测 SEL 位置。我们使用这种开发的非接触式技术来演示基于 SEL 的对人手指位置的高精度实时检测。
