Smart carpet makes home safer for elderly

The video tutorial explains the use of fiber optics in detecting changes in light received by sensors, which then relay signals to computers for analysis. It covers how patterns like footsteps can be detected and how the system can trigger alarms in case of falls. Additionally, it discusses potential applications in healthcare, such as monitoring patients' conditions in hospital beds by measuring temperature, moisture, or pH levels.

What happens to the fibers when weight is applied to a surface?

• They emit light.

• They become rigid.

• They change color.

• They bend, altering light reception.

How do sensors use the signals they receive?

• To emit sound.

• To analyze patterns like footsteps.

• To change the color of the fibers.

• To increase temperature.

What can the system do if it detects a fall?

• Send a text message.

• Trigger an alarm and call for help.

• Change the light color.

• Increase the room temperature.

In what setting could fiber optics be used to monitor patients?

• In hospital beds.

• In shopping malls.

• In schools.

• In public parks.

What parameters can fiber optics measure in a healthcare setting?

• Temperature, moisture, or pH levels.

• Sound levels.

• Light intensity.

• Air pressure.
