  • What's the fastest growing threat to Americans' health?

    在威脅美國人健康的疾病中, 增速最快的是哪種?

  • Cancer? Heart attacks? Diabetes?

    癌癥?心臟病?糖尿病?

  • The answer is actually none of these;

    其實都不是。

  • it's Alzheimer's disease.

    答案是失智症(阿爾茨海默病)。

  • Every 67 seconds,

    每隔 67 秒,

  • someone in the United States is diagnosed with Alzheimer's.

    美國就有一人被診斷出患有失智症。

  • As the number of Alzheimer's patients triples by the year 2050,

    而到 2050 年, 失智症患者的數量會翻三倍,

  • caring for them, as well as the rest of the aging population,

    照顧這些患者,以及其他老齡人口

  • will become an overwhelming societal challenge.

    將會成為巨大的社會挑戰。

  • My family has experienced firsthand

    我的家庭就有切身體驗,

  • the struggles of caring for an Alzheimer's patient.

    知道照顧失智症患者的辛苦。

  • Growing up in a family with three generations,

    我成長於三代同堂的家庭,

  • I've always been very close to my grandfather.

    從小就跟爺爺非常親近。

  • When I was four years old,

    當我四歲時,

  • my grandfather and I were walking in a park in Japan

    我跟爺爺在公園裡散步,

  • when he suddenly got lost.

    突然間他走失了。

  • It was one of the scariest moments I've ever experienced in my life,

    這是迄今為止最讓我害怕的回憶之一,

  • and it was also the first instance that informed us

    也是第一次使我們意識到,

  • that my grandfather had Alzheimer's disease.

    爺爺得了失智症。

  • Over the past 12 years, his condition got worse and worse,

    過去 12 年來,他的病情逐漸加重,

  • and his wandering in particular caused my family a lot of stress.

    尤其是他出去遊盪的時候, 全家都會很緊張。

  • My aunt, his primary caregiver,

    姑媽是爺爺的主要看護人,

  • really struggled to stay awake at night to keep an eye on him,

    她夜裡硬撐著不敢睡覺, 為了看住爺爺,

  • and even then often failed to catch him leaving the bed.

    即使這樣,也經常沒能阻止 爺爺下床。

  • I became really concerned about my aunt's well-being

    我開始非常擔心姑媽的健康

  • as well as my grandfather's safety.

    和我爺爺的安全。

  • I searched extensively for a solution that could help my family's problems,

    我廣泛搜尋,想要找到一個方法 可以幫助我的家人。

  • but couldn't find one.

    卻都以失敗告終。

  • Then, one night about two years ago,

    後來,兩年前的一個晚上,

  • I was looking after my grandfather and I saw him stepping out of the bed.

    我在照顧爺爺的時候, 看到他正想要下床,

  • The moment his foot landed on the floor,

    他的腳碰到地面的瞬間,

  • I thought, why don't I put a pressure sensor on the heel of his foot?

    我想到,為何不在他的後腳跟 放個壓力傳感器呢?

  • Once he stepped onto the floor and out of the bed,

    當他下床著地的時候,

  • the pressure sensor would detect an increase in pressure caused by body weight

    傳感器就能檢測到由於爺爺體重 而造成的壓力上漲,

  • and then wirelessly send an audible alert to the caregiver's smartphone.

    並能將警報信號通過無線網路 傳輸到看護人的智能手機。

  • That way, my aunt could sleep much better at night

    這樣一來,我姑媽晚上 就可以睡得更好一些。

  • without having to worry about my grandfather's wandering.

    不用一直擔心爺爺會到處走動。

  • So now I'd like to perform a demonstration of this sock.

    現在我來展示一下 我發明的壓力感應襪子。

  • Could I please have my sock model on the stage?

    能邀請我的襪子模特到臺上來嗎?

  • Great.

    很好。

  • So once the patient steps onto the floor --

    一旦病人的腳著地 ﹣﹣

  • (Ringing) --

    (警報聲)﹣﹣

  • an alert is sent to the caregiver's smartphone.

    警報就會被發送到看護人的智能手機上。

  • Thank you. (Applause)

    謝謝。(掌聲)

  • Thank you, sock model.

    謝謝這位模特。

  • So this is a drawing of my preliminary design.

    這就是我初步設計的草圖。

  • My desire to create a sensor-based technology

    我之所以想要創造一個 基於傳感器的技術,

  • perhaps stemmed from my lifelong love for sensors and technology.

    原因可能來自我對傳感器 和相關科技長期以來的熱愛。

  • When I was six years old,

    當我六歲時,

  • an elderly family friend fell down in the bathroom

    家裡有一位長者在浴室跌倒了,

  • and suffered severe injuries.

    並因此傷得很重。

  • I became concerned about my own grandparents

    我開始擔心祖父母的安全,

  • and decided to invent a smart bathroom system.

    並且決心要發明一套智能浴室系統。

  • Motion sensors would be installed inside the tiles of bathroom floors

    運動傳感器將會被嵌入在 浴室的地磚裡面,

  • to detect the falls of elderly patients whenever they fell down in the bathroom.

    當老人摔倒在地板上的時候 就能夠檢測到壓力。

  • Since I was only six years old at the time

    當時我才只有6歲,

  • and I hadn't graduated from kindergarten yet,

    幼稚園尚未畢業,

  • I didn't have the necessary resources and tools to translate my idea into reality,

    沒法獲取所需的資源和工具 來實現我的想法,

  • but nonetheless, my research experience

    儘管如此,我的研究經歷

  • really implanted in me a firm desire to use sensors to help the elderly people.

    讓我樹立起堅定的信念, 利用傳感器去幫助老人。

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

    我堅信傳感器可以提高 老年人的生活質量。

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

    當我開始細化我的計劃時, 我意識到我面臨著三大挑戰:

  • first, creating a sensor;

    第一,創造傳感器;

  • second, designing a circuit;

    第二,設計電路;

  • and third, coding a smartphone app.

    第三,寫出手機軟件。

  • This made me realize that my project was actually much harder to realize

    這讓我意識到,實現我的計劃 比我一開始想象的要難得多。

  • than I initially had thought it to be.

    首先,我需要發明一個可穿戴、 足夠輕薄靈活的傳感器,

  • First, I had to create a wearable sensor that was thin and flexible enough

    能讓病人舒適地穿在腳上。

  • to be worn comfortably on the bottom of the patient's foot.

    在廣泛地研究和嘗試了許多種材料之後, 比如橡膠,

  • After extensive research and testing of different materials like rubber,

    我意識到它們都太厚了, 穿在腳上不夠服帖。

  • which I realized was too thick to be worn snugly on the bottom of the foot,

    我決定打印一個薄膜式傳感器,

  • I decided to print a film sensor

    使用能感知壓力的電子墨水來構造。

  • with electrically conductive pressure-sensitive ink particles.

    一旦產生壓力,墨水粒子之間的 連通性就增加了。

  • Once pressure is applied, the connectivity between the particles increases.

    因此,我就可以通過測量電阻的方法,

  • Therefore, I could design a circuit that would measure pressure

    設計測試壓力的電路。

  • by measuring electrical resistance.

    接下來,我需要設計 可穿戴的無線電路。

  • Next, I had to design a wearable wireless circuit,

    但是無線信號傳輸非常耗電,

  • but wireless signal transmission consumes lots of power

    並且需要笨重的電池。

  • and requires heavy, bulky batteries.

    所幸我找到了低功耗的藍牙技術,

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

    耗电很少,紐扣電池就能夠發動起來。

  • which consumes very little power and can be driven by a coin-sized battery.

    這就避免了系統工作到半夜 就沒電的狀況。

  • This prevented the system from dying in the middle of the night.

    最後,我需要自己寫 一款智能手機軟件,

  • Lastly, I had to code a smartphone app that would essentially transform

    它將看護人的智能手機 變成遠程監控器。

  • the care-giver's smartphone into a remote monitor.

    為此,在 Java 和 XCode 知識的基礎上 我繼續鑽研編程,

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

    並自學了如何用代碼 去操縱藍牙低功耗設備,

  • and I also had to learn about how to code for Bluetooth low energy devices

    為此我看了很多的 YouTube 指導視頻 以及翻了很多書。

  • by watching YouTube tutorials and reading various textbooks.

    把這些組件拼接起來後, 我成功做出來了兩個原型,

  • Integrating these components, I was able to successfully create two prototypes,

    其中一個原型,傳感器被嵌入襪子裡,

  • one in which the sensor is embedded inside a sock,

    而另一個,傳感器則是可以拆卸的,

  • and another that's a re-attachable sensor assembly

    可以粘在病人腳底

  • that can be adhered anywhere that makes contact

    任何產生接觸的地方。

  • with the bottom of the patient's foot.

    我在爺爺身上試驗了大約一年,

  • I've tested the device on my grandfather for about a year now,

    它的準確率高達 100%,

  • and it's had a 100 percent success rate

    成功檢測到了我爺爺 超過 900 次的發病情況。

  • in detecting the over 900 known cases of his wandering.

    去年夏天,我開始在美國加州的 一些護理院試用這套設備,

  • Last summer, I was able to beta test my device

    目前我正在收集反饋,

  • at several residential care facilities in California,

    來進一步完善這個裝置, 使它成為可以進入市場的產品。

  • and I'm currently incorporating the feedback

    在一些病人試用的過程中,

  • to further improve the device into a marketable product.

    我意識到我需要創新解決方案,

  • Testing the device on a number of patients

    來幫助那些不想穿著襪子睡覺的人。

  • made me realize that I needed to invent solutions

    從大規模的病人身上 采集到的傳感器數據,

  • for people who didn't want to wear socks to sleep at night.

    不僅對於照顧病人有幫助作用,

  • So sensor data, collected on a vast number of patients,

    對於疾病本身的治療也可能會有幫助。

  • can be useful for improving patient care

    例如,我現在在檢測的是

  • and also leading to a cure for the disease, possibly.

    病人夜間活動的頻率

  • For example, I'm currently examining

    與白天的行為和飲食之間的關聯。

  • correlations between the frequency of a patient's nightly wandering

    我永遠忘不了

  • and his or her daily activities and diet.

    我的設備第一次成功檢測到 我爺爺半夜下床的時刻。

  • One thing I'll never forget is when my device first caught

    那一刻,我強烈地感受到了 科技的力量,

  • my grandfather's wandering out of bed at night.

    它能讓生活更加美好。

  • At that moment, I was really struck by the power of technology

    人們可以健康快樂地生活 ﹣﹣

  • to change lives for the better.

    那就是我夢想中的世界。

  • People living happily and healthfully --

    非常感謝。

  • that's the world that I imagine.

    (掌聲)

  • Thank you very much.

  • (Applause)
