- [00:00:02.060]Smart home technology has enabled
- [00:00:04.450]convenient lives for everyone in the United States,
- [00:00:07.850]around the world.
- [00:00:08.990]Alexa, how many feet in a mile?
- [00:00:11.953]One mile--
- [00:00:12.786]All these devices actually
- [00:00:13.760]are wirelessly connected to the internet.
- [00:00:16.140]If we have hundreds of connected devices,
- [00:00:19.130]you will start noticing your wireless performance
- [00:00:21.800]starting dropping significantly.
- [00:00:25.490]So here's a little transducer
- [00:00:27.720]that we developed with using a 3D printer.
- [00:00:30.820]Our transmitter and receiver prototype
- [00:00:33.670]uses ultrasound frequencies instead of radio frequencies.
- [00:00:37.920]The conventional wisdom think
- [00:00:39.680]that ultrasound cannot work over the air.
- [00:00:43.290]And we are breaking this conventional wisdom
- [00:00:46.210]to make it actually transmit over the air.
- [00:00:49.030]And it is very secure.
- [00:00:50.850]It is very reliable,
- [00:00:52.240]and have an extremely low energy consumption.
- [00:00:56.210]My lab has research opportunities for both
- [00:00:59.452]outstanding graduate students and undergraduate students.
- [00:01:02.480]So here this graph--
- [00:01:04.040]We focus on the new phenomenon
- [00:01:07.960]called IoT, internet of things.
- [00:01:11.240]Dr. Yan is the world expert
- [00:01:14.050]in the area of cybersecurity and IoT.
- [00:01:17.600]I'm so lucky to be his advisee because he's a true mentor.
- [00:01:24.020]In a world with so many distractions,
- [00:01:26.400]I hope that researchers in my lab can spend time
- [00:01:29.994]contemplating on the world issues and technologies
- [00:01:33.400]and to address them.
- [00:01:35.090]So UNL is a place where everyone has freedom
- [00:01:38.440]to think deeply for the society and the world.
- [00:01:41.980]And UNL has a mission to advance
- [00:01:44.920]the technology of the state and the world.
