multifunctional tactile sensing device

Abstract

The invention discloses a multifunctional touch sensing device, which includes an ultrasonic component, an intermediary buffer layer and an output component. Wherein, the ultrasonic component detects a contact object through the intermediary buffer layer connected with it, and the output component is electrically connected to the ultrasonic component, and generates at least one output image according to the detection result of the ultrasonic component. By comparing the output image with a reference image, the present invention can successfully find out what the pressure on the contacting object is. When there are multiple output images, the pressure on the contacting object can also be calculated by analyzing the differences of these images. With this kind of tactile sensing device, the present invention can simultaneously have the functions of pressure detection and image detection, and is a successful multifunctional tactile sensing device.

Description

technical field [0001] The invention relates to a tactile sensing device, in particular to a multifunctional tactile sensing device capable of simultaneously detecting image and pressure. Background technique [0002] Describe the background art on which the invention is based. The tactile sensing measurement system is similar to the function of a human finger. When in contact with an object, it can know the characteristics of the surface of the object and other physical property information, such as: the intensity and spatial distribution of force or pressure, the shape and position of the object, Characteristic information such as surface texture, temperature, softness or humidity. With the increasing prosperity and development of today's technology, the existing tactile sensing measurement system can be widely used in the industrial field, such as controlling robot actions (such as grasping objects), and combining displays as touch input devices , to achieve fingerprint...

Problems solved by technology

However, it is worth noting that most of the current technological backgrounds focus on multi-functionality and the integration of different technologies at the same time; when applying ultrasonic sensors to the field of tactile sensing, the When the image of the object and the pressure it bears, most of them need to use more than two sensors to complete. In view of this, as the number and functions of the sensors to be integrated become larger and larger, the burden on the overall sensing equipment will increase. Including: system integration, complexity, and production costs will also increase sharply, which will undoubtedly become a very serious problem in the prior art
