Title:
NOVEL ELECTRONIC SIGNATURE TOUCH PEN BASED ON STRESS LUMINESCENCE
Document Type and Number:
WIPO Patent Application WO/2020/010894
Kind Code:
A1
Abstract:
The present invention relates to the technical field of electronic signature devices, and disclosed is a novel electronic signature touch pen based on stress luminescence. The touch pen is provided with a tubular housing; a stress luminescence pen point is embedded in the center of the front end of the tubular housing; a micro-camera is embedded in the side surface of the front end of the tubular housing; a photoelectric converter is embedded in the rear end of the stress luminescence pen point; and a central processing chip and a signal transmitter are fixed in the tubular housing. The stress luminescence pen point directly emits electromagnetic wave light rays under the action of external force; the photoelectric converter collects light information emitted by the pen point; and a micro-lens fixed at the rear end of the pen point photographs a writing plane as a video signal and then transmits the light information and video information to an upper computer. Compared with a conventional signature pen, a signature contains not only information of pen point pressure and pen point friction but also speed information during signature; an image is not merely a two-dimensional signature image; the information reliability is improved; and the signature information security is further improved.
