Embodiment Construction
[0048] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.
[0049] First, a brief introduction to the nouns involved in the embodiments of this application:
[0050] Proximity sensor: It is a device capable of sensing the proximity of an object. Optionally, in the embodiment of the present application, a capacitive proximity sensor is used as an example for illustration. There is a certain capacitance between them. When the object approaches the electrode, the electrode is polarized by electrostatic induction, so that the electrode capacitance changes. According to the change of the electrode capacitance, the proximity of the object can be determined.
[0051] Optionally, in the embodiment of the present application, the proximity sensor includes a single electrode and a double electrode as...

The application, which relates to the field of sensor design, discloses a flexible sensing system, a proximity sensing method and device, an intelligent robot and equipment. The flexible sensing system comprises a first thin film packaging layer and a first electrode layer. The first electrode layer attached to the first thin film packaging layer includes double electrodes and a formed arc-shapedelectric field is used for determining a distance between a target object in a first distance range and the sensing system; and the first electrode layer further includes a single electrode and a formed vertical electric field is used for determining a distance between a target object in a second distance range and the sensing system, wherein the first distance range is less than the second distance range. According to the invention, the position of the object in the first distance range is determined through the double electrodes and the position of the object in the second distance range isdetermined through the single electrode, so that different sensing schemes are adopted for objects at different distance positions. Therefore, a problem of relatively low sensing accuracy of a singlesensing scheme is solved and the sensing accuracy of the proximity sensor is improved.
Description
[0001] The embodiments of the present application relate to the field of sensor design, in particular to a flexible sensing system, a proximity sensing method, device, intelligent robot and equipment. Background technique [0002] With the development of intelligent robot technology and the deepening of intelligent robot application scenarios, in addition to completing the set mechanical actions, intelligent robots also need to sense and give feedback to the external environment. Object perception, that is, when an object is close to the intelligent robot, the approach of the object can be sensed through the proximity sensor. [0003] In related technologies, an infrared sensor, a laser sensor or an ultrasonic sensor is used as a proximity sensor to be installed on an intelligent robot, and the distance between an object and the proximity sensor is determined by transmitting and receiving signals. [0004] However, when sensing objects in the above-mentioned way, since the sen...
