Introduction
In every corner of our lives, a group of tiny "detectives" are silently at work—they are microsensors. These small yet powerful devices, with their unique characteristics of miniaturization, low power consumption, and high sensitivity, are shining brightly in fields such as smart homes, healthcare, and environmental monitoring. Today, let us delve into the world of microsensors and explore their applications and future development directions.
Types of Microsensors: Diverse and Precise
Microsensors come in a wide variety, each like a specialized "soldier" in nature, tasked with capturing specific information.
Chemical Microsensors: These are the "detectives" of the chemical world, capable of accurately detecting the presence, concentration, or property changes of chemicals. For instance, ion sensors act like detectives uncovering the secrets of solutions, widely used in chemical analysis and environmental monitoring.
Biological Microsensors: Biological sensors are the "guardians" of life, utilizing biological recognition elements (such as enzymes, antibodies, DNA) to react specifically with the substance being measured, generating measurable signals. Gene sensors, for example, are like microscopes of biology, detecting specific gene sequences through DNA hybridization techniques, providing important tools for biomedical research and disease diagnosis.
Physical Microsensors: These sensors are the "translators" of physical quantities, converting changes in temperature, pressure, acceleration, and other physical parameters into electrical signals. For instance, surface acoustic wave (SAW) sensors are like sound catchers, utilizing SAW technology to achieve high-precision measurements.
