Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary function?Transduce physical phenomena into measurable electrical signals
2. What is the key historical development?Advancements in microelectronics and nanotechnology have enabled miniaturization and integration
3. What are sensors and why are they important?Sensors are tiny helpers that turn things like heat, light, or motion into electrical signals, letting computers understand the world around them.
4. How do sensors help in everyday gadgets like smartphones?Sensors in phones can feel motion, light, or sound, so the phone can change the screen brightness, play music, or help you navigate.

Transducer: A device that converts energy from one form to another.
