Introduction
According to American Lai this university official net reported recently, researcher uses this officer Xi of revulsive black lead makes laser a dynamo of attrition accept rice. This are flexible device can the electric energy of energy translate into that will move, make derive from power supply thereby can apparel sensor and equipment become a possibility.Setting
Nowadays, all sorts of can apparel the moves to cannot leave electric energy abidance of equipment is stable supply. It is means of traditional power supply with batteries, need charges often and add boat ability is limited, this also became an influence to be able to apparel equipment performance and one of crucial bottleneck that the user experiences.
Cast off batteries, let can apparel equipment collects energy from inside motion, already was new originality no longer. For example, the author ever had introduced the report since attrition device and the device that suppress report, the electric energy of energy translate into that they can carry human body movables is born.
Innovate
Recently, american Lai this a kind of data that university innovation gives, make can apparel the self-confessed report of equipment becomes more practical. Scientists learn periodical in American chemistry " ACS Nano " went up describe this project in detail.
Lai this the chemist of university lab Zhanmusi Tuer (James Tour) the black lead Xi with revulsive laser (LIG) application arrives not metallic is small-sized in equipment, these equipment can generate electricity. Resemble brushing a balloon on the hair same, mutual contact also can produce LIG composite material and other appearance electrostatic, these are electrostatic and usable at drive equipment.
Technology
Have electric effect through attrition, material can pass mutual contact and gain charge. Be put when them when parting again next together, exterior charge is accumulated ceaselessly, and these charge can be carried to generate electricity.
In the experiment, researcher people the fold LIG take join to arrive on a chain of glow diode, intercurrent show this to flap gently a belt, can produce the electric power that enough makes diode gives off light.
In embedding when bigger LIG person handwriting procrastinates when, the each pace of the person that apparel can produce electric power, because of black lead Xi composite material and skin contact meeting generation electric current repeatedly, charge for small-sized capacitor thereby.
Graph Er expresses: "This kind of means may be to use when walking sufficient accordingly, perhaps use the redundant energy that the arm produces at body brandish relatively, charge for small-sized device. Charge for small-sized device..
LIG is bubble of Xi of a kind of black lead. When polymer the apparently chemical material of other perhaps data is heated by laser, remain mutual connective only when 2 dimension carbon is chip, this kind of bubble was generated. The researcher of this lab is in above all get together commonly inferior a LIG is made on acyl amine, extend this technology plant, food and the paper that pass processing and lumber to go up again next.
Next, the researcher of this lab will get together inferior acyl amine, cork and electrode of LIG of other data translate into, go observing they produce energy and the result that experience daily loss. They from be located in attrition unripe cable unit achieved optimal result in the material of two end, these material were quantified generate electrostatic capacity through the report since the contact.
In folding configuration, get together by what negaive electricity carries after attrition inferior the LIG that acyl amine innovation goes, by spray covering layer of a polyurethane, this covering layer also regards the belt after attrition as the material of positive electricity. When these electrode gather, the electron comes by polyurethane move get together inferior acyl amine. Follow-up contact and depart, drive the charge that can store through exterior circuit, undertake be balancinged again handling to accumulative static charge. Folding LIG produces the tension that gives about 1 kilovolt, keep stable after curving a loop 5000 times.
Value
This optimal configuration, have get together inferior acyl amine - the electrode that LIG composite material and aluminium make, generated tension exceeds 3.5 kilovolt, peak value power exceeds tile of 8 fine long hair.
Paper lead author, Lai this the university is postdoctoral Stanford of · of researcher Michael Er (Michael Stanford) express: "Embed person handwriting pulls medium accept rice dynamo, can be in store on capacitor after 1 kilometre on foot 0.22 fine long hair the electric energy of joule. Memory of this kind of energy leads enough to be the sensor that can apparel and electronic parts power supply through human body motion. Memory of this kind of energy leads enough to be the sensor that can apparel and electronic parts power supply through human body motion..
Key word
Black lead Xi, laser, can apparel dynamo of rice of technology, self-confessed report, accept
