Have you ever wished that you were a superman?A person with superior visionA person with super memoryA person with zoom capability Time: 30 seconds(0:15-0:45)Say: Before I start my presentation, let me ask you a question.Have you ever wished that you were a superman? A superman with superior vision is able to see things very far away and has super memory that means you can never forget.Besides, a person can zoom in front of the scene with zoom capability.In other words, you could see the world around in front of your eyes as seen by protagonist in science fiction movies like Terminator and Robocop.Slide 3(Introduction):
This is now poible using Bionic contact lens！Appearance description:One of the smallest deviceWe could simply „BLINK‟ and than we will be onlineThe lens have infrared lights to create a virtual displayBionic Contact Lens Time: 40 seconds(0:45-1:25)Say: This is now poible using Bionic contact lens!We have established one of the smallest device.With this device, we would simply „BLINK‟
and we will be online.It‟s already more science than fiction.Especially, bionic contact lenses are being developed to provide a virtual display that could have a variety of uses from aisting the visually impaired to the video game industry.What‟s more, the lens will eventually have functional electronic circuits and infrared lights to create a virtual display.Slide 4(Introduction):
“The eye of the beholder”The beginning of the Computer Human InterfaceIt would tell you what is relevant and what to ignoreTranslation between languages at any timeComputer Human Interface Time: 35 seconds(1:25-2:00)Say: In next 20 years, internet will be on our contact lens as the picture shows.Bionic contact lens is this kind of device that could give a new meaning to the phrase “The eye of the beholder”.It could be the beginning of the Computer Human Interface of the future and your smart lens would tell you what is relevant and what to ignore.In addition, if someone speaks in Chinese, no problem, Bionic contact lens will translate Chinese into English subtitles underneath your picture.Slide 5(Body):
1.Generation principleConvert pieces of plastic and polymer to a functional systemAntenna picks up radio frequency energyChip harvests the energyTransmit information directly on the lensTransform it into voltage Time: 40 seconds(2:00-2:40)Say: First of all, let's see how it works!Firstly, bionic contact lens converts pieces of plastic and polymer to a functional system that resemble a kind of complexity in cellular form, and antenna picks up radio frequency energy that is transmitted by an antenna elsewhere.Then, while chip harvests the energy and transforms it into voltage that can power the LED.Finally, voltage works to display directly on the lens that would transmit information directly on the lens.Slide 6(Body):
2.Core Technology1)The micro fabrication technique2)Energy3)Virtual display technology4)Image technology Time: 25 seconds(2:40-3:05)Say: Any advanced device has its core technology, including bionic contact lens.Bionic contact lens contains many of the most advanced technologies, such as capillary forces, Antenna, Chip, Fresnel lenses and so on.Among them, the core technology can be summarized as the following four aspects.Slide 7(Body):
1)The micro fabrication techniqueBuild the circuits from layers of metal only a few nanometers thickConstruct light-emitting diodes one third of a millimeter acroArray of LED pixels is used in lens to form an active display Time: 50 seconds(3:05-3:55)Say: Next, let's look at the first aspect.Micro fabrication technique is used for image formation.We built the circuits from layers of metal only a few nanometers thick, about one thousandth the width of a human hair, and constructed light-emitting diodes one third of a millimeter acro.Simultaneously, array of LED pixels is used in lens to form an active display.Therefore, the shape of each tiny component dictates which piece it can attach to, and a micro fabrication technique known as self-aembly.Slide 8(Body):
2)EnergyFirstly: Antenna picks up radio frequency wavesThen: Turn them into energy Finally: Chip harvests the energy and transforms it into voltage Time: 40 seconds(3:55-4:35)Say: For the second aspect, Since this device is very small, the supply of energy is a key technical problem.As shown in this flowchart.Firstly, antenna picks up radio frequency waves and then turn them into energy that is transmitted by an antenna elsewhere.Finally, while chip harvests the energy and transforms it into voltage that can power the LED.The voltage is also a very small laser that can be used to ensure that the image is in focus at all times and eliminate the need for micro lenses.Slide 9(Body):
3)Virtual display technologyUsing a raster displayDisplayed on the retina of the eyeVirtual Display Image Time: 45 seconds(4:35-5:20)Say: Then, the third aspect is virtual display technology.A virtual retinal display, also known as a retinal scan display or retinal projector, is a display technology that draws a raster display directly onto the retina of the eye.In bionic lens, the display is floating in front of the user using virtual display technology.Certainly, it is not poible to display an image over a solid angle from a point source unle the projection system can bypa the lenses within the eye.Slide 10(Body):
4)Image technologyImage qualityFresnel lensesImage managementPixel management Time: 60 seconds(5:20-6:20)Say: Finally, the core technology is to say that Image technology.It is mainly related to these four points on the slide.In terms of Image quality , we overcome that obstacle by precisely adjusting the angle of incoming light emitted by diodes on the contact lens.For Fresnel lenses and Image management, we tackled the limitation of the minimum focal distance of the human eye by incorporating a set of Fresnel lenses into the device.For Pixel management, we have provided the first proof-of-concept technology demonstrations for producing multipixel and in-focus images.Slide 11(Body):
3.Critical ApplicationsZooming in on and out of distant objectsPersonalized wide-screen TVVisual aids for vision-impaired peopleBio-sensing--monitor health care Immersive video gamesDirection-to orient and identify landmark on the map Time: 45 seconds(6:20-7:05)Say: In the previous section, we have just talked about the generation of bionic contact lens and its core technology, then we talk about what are the critical applications.As shown on the slide, it consists mainly of six points.For example, zooming in on and out of distant objects-It means we would be able to zoom in on something far away or to look at something very close;And personalized wide-screen TV-It means the combination of contact lens with embedded optoelectronic and electronic devices could well be the beginning of the Computer Human Interface of the future.As time is limited, the following four points I will not explain in detail.Slide 12(Body):
4.Technical BottlenecksAttach the electronic components thinner than a human hairAre materials safe for use in the body?Focus on image qualityGive power supply Time: 40 seconds(7:05-7:45)Say: Although the application of good prospects for bionic contact lens, there are still several technical bottlenecks.First challenge is how to attach the electronic components thinner than a human hair.The next problem is building the lenses is a challenge because materials that are safe for use in the body are delicate.What‟s more, how to focus on image quality and how to give power supply are both the big obstacle.In addition to these points, there are other problems we need to work hard to resolve.Slide 13(Conclusion):
ConclusionThe era of bionic contact lens is coming soon--With advanced core technology--Very good application prospectsTechnical bottlenecks to be solved Time: 25 seconds(7:45-8:10)Say: As I end，the era of bionic contact lens would soon come.According to the introduction of the previous point of view, bionic contact lens with advanced core technology has a very good application prospects.However, there are still some bottlenecks to be resolved because of the technical problems so far.Slide 14(Conclusion):
Conclusion : Why is this significant?The beginning of the Computer Human Interface of the future--Surfing the Web at any time--Keeping the information connection all the timeA person can record their entire lifeOne day lead to everyone having beyond perfect vision Time: 35 seconds(8:10-8:45)Say: In short, bionic contact lens has a cro-era significance.One of the most important is bionic contact lens could be the beginning of the Computer Human Interface of the future when we could surf the Web at any time or keep the information connection all the time.Furthermore, a person could record their entire life just by blinking or poibly connect their contact lenses with a wirele device, and we would witne the day when everyone has the perfect vision.Slide 15(Conclusion):
