Embodiment 1

[0052] figure 1 Shown is a typical structure of the smart button based on friction electrification of the present invention, including sensing components, the sensing components include: an insulating layer 3, an upper electrode layer 2 and a lower electrode layer respectively attached to the upper and lower surfaces of the insulating layer 3 The electrode layer 3 and the touch layer 1 bonded on the upper electrode layer 2 . The touch layer 1 is contacted by the knocking object, and an electrical signal is generated between the upper electrode layer 2 and the lower electrode layer 4, which can be detected by the detection element 5 connected between the upper electrode layer 2 and the lower electrode layer 4; wherein, the touch layer 1 The material of the knocking object has different ability to gain and lose electrons on the surface of the material.

[0053] The knocking object described here can be materials such as fingers or natural latex gloves that can be triboelectrica...

Embodiment 2

[0068] In this embodiment, the smart keys in Embodiment 1 are used to form a smart keyboard, see image 3 , including a plurality of intelligent keys K1, K2, K3...Kn, which are arranged according to the arrangement rules of the keyboard to form a required intelligent keyboard. Each smart key is individually connected to a signal detection element 51, 52, 53...5n. When any key in the keyboard is tapped by a finger, the signal detection element will detect an electrical signal. The touch layer 1 of multiple smart keys K1, K2, K3...Kn can be independent of each other, see image 3 , can also be connected together, see Figure 4 .

[0069] The size of each button can be the same or different.

[0070] In other embodiments, the insulating layers 3 of multiple smart keys may also be connected together.

[0071] Similarly, the smart keyboard of this embodiment can be used alone as a keyboard, or it can be attached to an existing keyboard body and used in combination.

Embodiment 3

[0073] In addition to being used as a keyboard, the smart keyboard of this embodiment can also be used as a positioning signal for the electrical signal generated by keystrokes to locate the keystrokes. as attached Figure 5As shown, it includes several smart buttons K1, K2, K3..., and a 1 megohm resistor R is connected between the upper electrode layer 2 and the lower electrode layer 4 of each button, and each resistor R is connected to each smart button. One end of the lower electrode layer 4 is connected to a common ground end, and the other end of each resistor R is respectively connected to a signal output end A1, A2, A3.... In this way, each keystroke can be independently recognized at the output end, and through the programming setting of Labview, the tracking and recognition of the input is further realized.

[0074] In addition, the electrical signal detected by the output terminal is related to the keystroke rhythm, keystroke habit, finger size, personal bioelectric...

Abstract

The invention provides a triboelectrification-based intelligent key and an intelligent keyboard. The intelligent key comprises a sensing component; the sensing component comprises an insulating layer, an upper electrode layer and a lower electrode layer stuck to the upper and lower surfaces of the insulating layer separately, and a touch layer stuck to the upper electrode layer; the touch layer is in contact with a knocking object to generate electrical signals between the upper electrode layer and the lower electrode layer; and the surfaces of the materials for the touch layer and the knocked object have different electron gaining and losing capabilities. Correspondingly, the invention further provides a touch pen used with the intelligent key and the intelligent keyboard, wherein the materials for a contact of the touch pen and the touch layer have different electron gaining and losing capabilities. The mechanical energy of knocking the keyboard can be directly converted into electrical signals via the sensing component to drive a wireless transmitting device to realize alarm of the keyboard. A resistor is arranged in each key of the keyboard and connected with an output end, so that the keystroke position of the keyboard can be positioned and the keystroke mode can be identified.

Description

technical field [0001] The invention relates to an electronic device, in particular to an intelligent key and keyboard capable of identifying the keystroker. Background technique [0002] Keyboard, as an integral part of computer system, is a key component of human-computer interaction, such as information storage, reading, bank bill management, bill payment, personal communication, keyboard is an essential tool. Infringement of computer information will disrupt people's normal life, disrupt business order, and even endanger national security. The security of traditional computer systems depends on passwords, passwords, etc., but these protection measures are very limited, because it is easy for others to illegally obtain passwords to crack the security protection of computer systems. Contents of the invention [0003] The object of the present invention is to provide a keyboard capable of converting the mechanical force of a finger tapping the keyboard into an electrical...
