Specific embodiment:
A kind of wearable wireless mouse based on flexible electronic skin, including hand signal collecting unit, character recognition list
Unit, single-chip microcomputer, wireless telecommunication system and battery；
Described hand signal collecting unit includes flexible electronic skin, gesticulates the back of the hand motion during various gesture for collection and produces
Raw strain, and export as electronic signals；
Described hand signal collecting unit, critical piece is flexible electronic skin, the manufacture method of flexible electronic skin
For:Cu nano wire-graphene film is cut the strip of 2cm × 0.5cm, two ends elargol is stained with copper cash, more embedded PDMS
In, it is placed in 2h in 70 DEG C of air dry ovens, make flexible electronic skin.Wherein, the preparation method of Cu nano wire-graphene film
As follows:
(1) add 20-42mgCu nano wire in 20-25mL ethylene glycol solution, after being uniformly dispersed, add 48-54mg anti-bad
Hematic acid, adds 3-3.8mL graphene oxide after being uniformly dispersed, moves in hydrothermal reaction kettle, is placed on 120-160 DEG C of air blast and does
React 4-6h in dry case, be cooled to room temperature, just obtain Cu nano wire-Graphene composite aquogel.

16h, further takes out to pour in 150mL deionized water and is uniformly dispersed, and obtains suspension, then with core defecator sucking filtration, just obtains
Cu nano wire-graphene film.
Flexible electronic skin has higher susceptiveness and stability, and its shapes and sizes can be according to each back of people's hand
Feature is customized it is ensured that flexible electronic skin can be close to the top of the back of the hand, and vibration during gesture is gesticulated in sensitive collection.
Described character recognition unit is used for the number of the signal of hand signal collecting unit collection and storage in its data base
According to comparing, character recognition is realized according to artificial neural network algorithm；
Data base is set up by training, uses front in user, first has to be made completely according to user's the back of the hand feature
Flexible skin sensor can be made to be close to the intelligent apparatus above the back of the hand.Then need payment user to be trained, met
The mouse action gesture vibration signal of telecommunication of user action custom, these signals are set up a data base.
In identification process, stick the intelligent apparatus meeting oneself the back of the hand feature of our designs, when user gesticulates gesture
When, because the change of the back of the hand motion makes the back of the hand four weekly assembly produce vibration, the flexible skin sensor being close to the back of the hand is followed simultaneously
The vibration of the back of the hand can produce the Light deformation on surface, thus causing the deformation of foil gauge in resistance strain gage sensor so that straining
Sheet resistance values change, so that the magnitude of voltage of externally output also can change on foil gauge, this voltage signal is input to

The digital quantity of each gesture feature.Single-chip microcomputer obtains the digital quantity reflecting each gesture feature, by the ANN of identification
The recognizer of network, the signal in data base and these signals is carried out matching identification one by one, the result being identified.The present invention
In data base, on the one hand need to be stored in the current signals of various demonstration action names, it is right therewith to be on the other hand also required to be stored in
The current signal of the function choosing-item answered.
Described single-chip microcomputer is that the character identifying character recognition unit is compiled into corresponding binary code, and control signal is sent out
Penetrating module and send corresponding control signal, being received thus being controlled to computer by signal receiving module.In character recognition unit
After end of identification, recognition result enters single-chip microcomputer, and the character of identification is compiled into a binary coding, the telecommunications of each gesture
Number corresponding binary coding of waveform is different, and that is, hand signal identification database corresponds to a binary coded data storehouse.
Signal receiving module receives signal and the coding of signal will be decoded according to the agreement being set, and then realizes to electricity
The corresponding mouse action action of brain.In the present invention, single-chip microcomputer, wireless telecommunication system are all based on prior art.Wireless telecommunications system
System equally uses short-distance wireless communication agreement, is IrDA protocol, bluetooth communication agreement, Wi-Fi communications protocol, RF communication
Agreement, ZigBee communications protocol, NFC agreement, UWB communications protocol.Specific implementation process：User pastes on the back of the hand
Our flexible electronic skin upper, forefinger touches the gesture that desktop is " click left button ", and system is by the electrical signal wave collecting
Shape is input in character database and is identified, and identifies the signal waveform of " click left button " this gesture, and this is believed by single-chip microcomputer
Binary coding number corresponding to waveform inputs in the circuit of wireless telecommunication system, and computer identifies " click left button " and executes behaviour
Make.User then stretches out middle finger and touches the gesture that desktop ratio marks " click right ", and system is realized to electricity through same process
Brain clicks on the operation of right mouse button.User then stretches out forefinger and is placed on desktop to slide to the left, is formed different using forefinger and middle finger
Angle, corresponding mouse is moved to the left corresponding distance, and system realizes mobile Mus through same procedure identification " sliding to the left "
Target operates.
