Realizing method for low value touch interaction interface based on scam probe microscope

Abstract

Through operation computer and Ethernet, joystick of touch sensation device being as interactive interface transfers information of motion sent from joystick by operator to SPM control unit in control computer. SPM control unit controls motion of SPM probe so as to implement operation on object in Nano size. Through SPM control unit in control computer and Ethernet, each kind of information as feed back signal from SPM is transferred to operation computer with control program being stored. Converting each kind of information from SPM to signal of force, the control program feeds back the magnified signal of force to operator through joystick. The invention adds tactual sense about appearance and property in under Nano size. Features are: low cost, easy of development, and wide application.

Description

technical field [0001] The invention relates to perception, operation and processing technology at the nanoscale, in particular to a method for realizing a tactile interaction interface based on a scanning probe microscope. Background technique [0002] Nanotechnology is an emerging field of scientific research. Operation and processing at the nanoscale is an important part of nanotechnology. Only under the premise of operability, can we study the various physical and chemical properties of substances at the nanoscale, and develop advanced technical equipment such as nanodevices, nanosensors, and nanocomputers. Therefore, nanomanipulation is a hotspot in the current frontier research of international micro-nano technology. However, the existing equipment for nanotechnology research is basically based on the mechanism of SPM (scanning probe microscope, which is a kind of nano observation system; such as: scanning tunneling microscope STM or atomic force microscope AFM). Ex...

Problems solved by technology

[0003] Some foreign scientific research institutions had the idea of ​​embedding a Haptic device (a multi-degree-of-freedom electromechanical device for human-computer interaction) on the nano-observation system to realize the idea of ​​nano-operation based on human-computer interaction, but the Haptic device used The price is often more than 20,000 US dollars, such as the SENSABLE company's The price of the Premium 6DOF device is 80,000 US dollars, and the Delta 3-DOF device of the Swiss company ForceDimension is 85,000 US dollars. Such expensive prices have greatly hindered the widespread application of force-sensing nano-manipulation methods.
