This is a tiny device, called a nano-electro-mechanical device, that can be used for sensing substances in the air. It is made using advanced techniques on a semiconductor material with several layers, including metal electrodes and an oxide layer.
The device has two main parts, called electrodes, which are separated by a small air gap. When a voltage is applied, the top electrode can move down to touch the bottom one, creating an electrical contact.
In one version, the device is designed to detect specific substances in the air. It has a special organic layer on top that absorbs these substances. When the substance is absorbed, it changes the device's properties, allowing it to detect the presence of the substance. The absorbed molecules can be removed by applying a voltage, resetting the device.
The method to make this device involves several precise steps, including layering materials, using special coating processes, and patterning the electrodes with techniques like electron beam lithography. The result is a sensitive and tiny device capable of detecting airborne substances.
