TE Connectivity focuses on the behind-the-scenes story series of technological innovation
No matter how small it starts, every connection has the potential to create a more far-reaching impact. TE Connectivity highlights the stories behind technological innovation and shares how technological development contributes to a safer, sustainable, efficient and connected world.
From sending New Year greetings over WeChat voice messages, recording karaoke, to smart stethoscopes, we deal with voice devices almost every day. Did you know that this widely used recording technology is mostly based on the thin-film electret microphone developed by Dr. James West?
Click on the video to learn how he made recording, once an expensive product, accessible to everyone.
Before him, recording and sharing sound had always been an expensive “magic technology” because condenser microphones required bulky and expensive high-voltage batteries.
Dr. James West and his research partners found a dielectric material called Teflon that has its own charge and can convert sound into electrical signals. Based on this, they invented an economical, compact and highly sensitive thin-film electret microphone.
Sound is full of stories and legends. Every time you capture a wonderful moment in life, you establish a connection with James West's unknown technological story.
Airports, subway stations, train stations... Scanning security technology makes us feel safe and secure in public places with a lot of problems, and this is largely due to Dr. Manijeh Razeghi's research on the application of terahertz waves.
Watch the video to learn how security scanning technology is creating a safer world.
Terahertz has always been a less popular wavelength in the scientific community, but Dr. Razeghi sees extraordinary possibilities in it.
Dr. Manijeh Razeghi discovered a new semiconductor material, indium phosphide, that enabled the previously "impossible" in a device as small as a lunch box: the use of terahertz at room temperature. Terahertz helps us to look inside objects and see the world as never before.
You see, every security check or body X-ray relies on the active exploration of Dr. Manijeh Razeghi, a daring quantum physicist.
Traveling, working overtime, or traveling for work, who is watching over your home when you are not at home? Marie Van Brittan Brown invented the home security system because of the same concern.
Click on the video to learn how a mother's concern led to the birth of a home security system.
She is a mother and a nurse in Queens, New York. Like millions of other mothers around the world, she hopes to know whether her baby is safe at home during breaks from her busy work.
So, she and her husband, who was an electronics technician, built a complete radio control system: with multiple small holes at different heights, a two-way microphone, a remote door lock and an emergency button that could notify the police - this was the prototype of the modern home security system and the world's first surveillance camera.
So, every time you check on your cat to see if it's being naughty, or just say "hi" to your family while sitting at your desk, you're connecting to Marie Van Brittan Brown's untold story of technology.
