Making the Invisible Visible: The Magic of Wireless Sensing

Have you ever wondered how your iPhone can find an AirTag hidden under the couch? This demo reveals the “magic” behind the scenes—wireless sensing! We’ll show that wireless signals, like Wi-Fi, can do much more than connect you to the Internet. They can sense motion, detect heartbeats, and even see through smoke, fog, or walls. Using simple hands-on demonstrations, kids will explore how invisible waves can make the world around us “visible” in new ways. This interactive session will spark curiosity and inspire young scientists to explore the exciting world of STEM.

Presented by:

  • Ruofeng Liu, Assistant Professor, Computer Science and Engineering, MSU
  • Fangwe Zhang, Graduate Assistant, Computer Science and Engineering, MSU

Suggested for ages: Kindergarten and Pre-K, Elementary school age, Middle school age, High school age, 18 years and above
