Defining Sensors
Sensors are devices that detect events or changes in the environment and send the information to other electronics, typically a computer processor.
Sensor Evolution
Early sensors were simple mechanical devices. Today, they have evolved into complex, miniaturized systems with applications ranging from smartphones to space probes.
Types of Sensors
Sensors come in many types, such as temperature, pressure, motion, and light sensors, each designed for specific purposes and distinct ways of operation.
Bio-inspired Sensing
Some advanced sensors mimic nature. For example, biomimetic sensors replicate bats' echolocation to detect objects in autonomous vehicles.
Smart Sensors
Smart sensors possess integrated computing resources, capable of performing certain tasks without additional processing power, such as filtering or data analysis.
Sensors in Medicine
Innovative medical sensors can monitor vital signs, detect diseases at early stages, or even dissolve in the body after fulfilling their purpose.
Environmental Impact
Sensors monitor pollution, track wildlife, and forecast natural disasters. This crucial data helps in protecting and managing the environment sustainably.
