Solid-state sensors are electronic devices that detect physical phenomena, such as temperature, pressure, or light, using solid materials instead of moving parts. They convert these phenomena into electrical signals, making them highly reliable and durable. Common examples include temperature sensors and pressure sensors, which are widely used in various industries, including automotive and healthcare. These sensors are often preferred for their compact size and low power consumption. Unlike traditional sensors, solid-state sensors can operate in harsh environments and have a longer lifespan. Their applications range from smartphones to industrial automation, showcasing their versatility in modern technology.
