Glass is a perfect choice in many applications. One of them is micromechanics. Femtika team demonstrated a compliant mechanism called a bistable switch. It is wholly made out of fused silica glass using selective laser-assisted etching (SLE) technique. The mechanism moves due to elastic deformations of 20 µm thickness arms. A bistable switch has two stable positions which could be switched by actuating it with a needle. The total size of the structure is 5 x 9 mm.
Some specific examples of applications for bistable switches:
- Level control: Bistable switches can be used to control the level of liquid or solid materials in a tank or container. For example, a bistable switch can be used to turn on a pump when the liquid level in a tank is low, and turn off the pump when the liquid level is high.
- Security systems: Bistable switches can be used in security systems to detect intruders or other security breaches. For example, a bistable switch can be used to detect when a door or window is opened.
- Medical devices: Bistable switches can be used in medical devices to control the flow of fluids or gases. For example, a bistable switch can be used to control the flow of oxygen to a patient.
- Transportation: Bistable switches can be used in transportation systems to control the movement of vehicles and other equipment. For example, a bistable switch can be used to control the opening and closing of a railway crossing gate.
Bistable switches are a versatile and reliable type of switch that can be used in a wide variety of applications. They are an essential component in many modern electronic systems.
