Šezdeset posto ljudi koji pate od senilnosti često odluta. To je problem koji može biti iznimno stresan i za pacijente i za njegovatelje. U ovom šarmantnom govoru poslušajte kako je tinejdžerski inovator Kenneth Shinozuka osmislio novo rješenje kako bi pomogao svom djedu, noćnom lutalici, i svojoj teti koja o njemu brine... i kako se nada da će pomoći i drugima oboljelim od Alzheimerove bolesti.

01:00
Over the past 12 years,
his condition got worse and worse,

Tijekom zadnjih 12 godina stanje mu se
sve više i više pogoršavalo,

01:07
My aunt, his primary caregiver,
21
55823
1479
Moja teta, djedova primarna skrbnica,
01:09
really struggled to stay awake at night
to keep an eye on him,

22
57302
3047
mučila se ostajući budna
kako bi pazila na njega

01:12
and even then often failed
to catch him leaving the bed.

23
60349
2698
i opet često ne bi ni primijetila kako
izlazi iz kreveta.

01:15
I became really concerned
about my aunt's well-being

24
63047
2811
Jako sam se počeo brinuti i za tetinu
dobrobit

01:17
as well as my grandfather's safety.
25
65858

i za djedovu sigurnost.
01:19
I searched extensively for a solution
that could help my family's problems,

67599

Predano sam tražio rješenje koje bi moglo
pomoći problemima moje obitelji,

01:23
but couldn't find one.
27

1360
ali nisam ga mogao naći.
01:24
Then, one night about two years ago,
28
72960
2733
Onda jedne noći prije neke dvije godine
01:27
I was looking after my grandfather
and I saw him stepping out of the bed.
and I saw him stepping out of the bed.
29
75693
3465
pazio sam na djeda i vidio sam ga kako
izlazi iz kreveta.
izlazi iz kreveta.
01:31
The moment his foot landed on the floor,
30
79158
1992
U trenutku kad mu je stopalo dotaklo pod,
01:33
I thought, why don't I put
a pressure sensor on the heel of his foot?
a pressure sensor on the heel of his foot?
31
81150
3262
pomislio sam: mogao bih mu na petu
postaviti senzor za pritisak.
postaviti senzor za pritisak.
01:36
Once he stepped onto the floor
and out of the bed,
and out of the bed,
32
84412
2397
Kad bi iskoračio iz kreveta i stao na pod,
01:38
the pressure sensor would detect an
increase in pressure caused by body weight

33
86809
3707
senzor za pritisak očitao bi povećanje u
pritisku uzrokovano tjelesnom težinom

01:42
and then wirelessly send an audible alert
to the caregiver's smartphone.

34
90516
3455
i zatim bežično poslao zvučno upozorenje
na smartphone njegove skrbnice.

01:45
That way, my aunt could sleep
much better at night

35
93971
2341
Tako bi moja teta mogla puno bolje spavati
01:48
without having to worry
about my grandfather's wandering.
about my grandfather's wandering.
36
96312
2690
ne morajući se brinuti o djedovom lutanju.
01:51
So now I'd like to perform
a demonstration of this sock.

37
99002

Sad bih volio izvesti demonstraciju
ove čarape.

Could I please have
my sock model on the stage?

02:00
Great.
39

Odlično.
02:04
So once the patient
steps onto the floor --

Kad pacijent stane na pod --
02:07
(Ringing) --

02:24
So this is a drawing
of my preliminary design.

Moja želja za stvaranjem tehnologije

02:30
perhaps stemmed from my lifelong love
for sensors and technology.

vjerojatno je potekla od moje cjeloživotne
ljubavi prema senzorima i tehnologiji

02:33
When I was six years old,
48
141979
1486
Kad sam imao šest godina.,
02:35
an elderly family friend
fell down in the bathroom

stariji obiteljski prijatelj pao je
u kupaonici

and suffered severe injuries.

145795

i zadobio teške ozljede.
02:39
I became concerned
about my own grandparents

51
147505
2101
Zabrinuo sam se za vlastite bake i djedove
02:41
and decided to invent
a smart bathroom system.

52
149606
2352
i odlučio izumiti pametan
kupaonski sustav.

02:43
Motion sensors would be installed
inside the tiles of bathroom floors

02:47
to detect the falls of elderly patients
whenever they fell down in the bathroom.

kako bi detektirali padove starijih
pacijenata kad god bi pali u kupaonici.

02:51
Since I was only six years old at the time

Budući da sam tada imao samo šest godina
02:53
and I hadn't graduated
from kindergarten yet,

161416
2323
i još nisam završio ni vrtić,
02:55
I didn't have the necessary resources and
tools to translate my idea into reality,

nisam imao potrebne resurse i alate

03:00
but nonetheless, my research experience
58
168073
2633
Kako bilo, ovo istraživačko iskustvo
03:02
really implanted in me a firm desire
to use sensors to help the elderly people.

u meni je uistinu usadilo snažnu želju za

I really believe that sensors can improve
the quality of life of the elderly.

Uistinu vjerujem da im senzori mogu

03:12
When I laid out my plan, I realized
that I faced three main challenges:

61
180944
3481
Kad sam izrađivao plan, shvatio sam da
postoje tri osnovne poteškoće:

03:16
first, creating a sensor;
62
184425
1769
prva, stvaranje senzora;
03:18
second, designing a circuit;
63
186194
1579
druga, dizajniranje strujnog kruga;
03:19
and third, coding a smartphone app.
64
187773
1746
i treća, kodiranje aplikacije.
03:21
This made me realize that my project
was actually much harder to realize

65
189519
3408
Tada sam shvatio da je moj projekt
teže realizirati
teže realizirati
03:24
than I initially had thought it to be.
66
192927
2055
nego što sam u početku mislio.
03:26
First, I had to create a wearable sensor
that was thin and flexible enough

67
194982

Prvo sam morao napraviti tanak nosivi

on the bottom of the patient's foot.

3535
za koju sam shvatio da je predebela

03:40
I decided to print a film sensor

odlučio sam isprintati filmski senzor

3576
Kad dođe do pritiska,
povezanost među česticama se povećava.

03:48
Therefore, I could design a circuit
that would measure pressure

74
216236
2964
Stoga sam mogao dizajnirati strujni krug
koji bi mjerio pritisak

by measuring electrical resistance.

Next, I had to design
a wearable wireless circuit,

Zatim sam trebao dizajnirati
bežični strujni krug,

Thankfully, I was able to find out
about the Bluetooth low energy technology,

Zahvaljujući ovome, sustav

04:11
Lastly, I had to code a smartphone app

04:17
For this, I had to expand upon
my knowledge of coding with Java and XCode

3676
Za to sam trebao proširiti svoje znanje
o kodiranju u Javi i XCodeu

04:21
and I also had to learn about how to code

ABOUT THE SPEAKER
Kenneth Shinozuka - Smart product inventorKenneth Shinozuka designs smart products ... He's been doing so since he was in kindergarten.
Why you should listen
When he was six years old, a family friend of Kenneth Shinozuka fell down in the bathroom. The friend was ok -- but the incident inspired him to design a motion detection system that could be embedded in bathroom tiles. He never actually made one in real life (remember, he was only six) ... but he was hooked on both the promise of invention and the potential of technology.
Since then, Shinozuka has designed smart devices for his grandfather, who has Alzheimer's disease. One invention that caught the eye of both the media and awards programs such as the Google Science Fair: a pair of smart socks, designed to send an alert to a caregiver if a patient gets out of bed. In 2014, he won the $50,000 Scientific American Science in Action Award, while he was also a 2014 Davidson Fellow.
