)Batteries can power anything from small sensors to

large

scientists

are

finding

ways

to

make

them

smaller

but

even

more

powerful

，

problems

can

arise

when

these

batteries

are

much

larger

and heavier than the devices sity of

Missouri(MU)researchers are developing a nuclear energy source that is

smaller

，

lighter and more efficient.

“

To provide enough power

，

we need certain methods with high energy

densit y(

密度

)

”

，

said Jae Kwon

，

assistant professor of electrical and

computer engineering at MU.

“

The radioisotope(

放射性同位素

)battery can

provide power density that is much higher than chemical batteries.

”

Kwon and his research team have been working on building a small

nuclear battery

，

presently the size and thickness of a penny

，

intended

to

power

various

micro

/

nanoelectromechanical

systems

(M/NEMS)

、

Although

nuclear batteries can cause concerns

，

Kwon said they are safe.

“

People hear the word

‘

nuclear

’

< br> and think of something very

dangero us

，

”

he

said

，

“

However

，

nuclear

power

sources

have

already

been

safely

powering

a

variety

of

devices

，

such

as

pace

?

makers

，

space

satellites

and underwater systems.

”

His new idea is not only in the battery's size

，

but also in its

semiconductor(

半导体

)

、

Kwon's

battery

uses

a

liquid

semiconductor

rather

than a solid semiconductor.

“

The

key

part

of

using

a

radioactive

battery

is

that

when

you

harvest

the

energy

，

part

of

the

radiation

energy

can

damage

the

lattice

structure

(

晶体结构

)of the solid semiconductor

，

”

Kwon said

，

“

By using a liquid

semiconductor

，

we believe we can minimize that problem.

”

Together

with

J

、

David

Robertson

，

chemistry

professor

and

associate

director of the MU Research Reactor

，

Kwon is working to build and test

the the future

，

they hope to increase the battery's power

，

shrink its size and try with various other said that

battery could be thinner than the thickness of human hair.
