Smartdust [1] is a system of many tiny microelectromechanical systems (MEMS) such as sensors, robots, or other devices, that can detect, for example, light, temperature, vibration, magnetism, or chemicals.
The magnet induces an electric current as it spins around the red copper winding, seen on the lower right. The current from the copper winding flows through the filament of an incandescent light bulb (not shown), giving off light. An L-shaped spring returns the handle to its original position after each engagement.
A magnetic applicator is used in place of a fingerprint brush composed of fibers. [3] The magnet within the applicator attracts the magnetic powder, forming a cluster of powder that can be gently moved across the fingerprint. Once complete, the magnet within the applicator is retracted and the magnetic powder falls off. [3]
A set of modern LED flashlights. A flashlight or electric torch (Commonwealth English), usually shortened to torch, is a portable hand-held electric lamp.Formerly, the light source typically was a miniature incandescent light bulb, but these have been displaced by light-emitting diodes (LEDs) since the early 2000s.
Ferrofluid is a liquid that is attracted to the poles of a magnet.It is a colloidal liquid made of nanoscale ferromagnetic or ferrimagnetic particles suspended in a carrier fluid (usually an organic solvent or water). [1]
The Mag Kid is a small magnet centered on the touchscreen. The Slide Controller is attached to Slot 2 of the DS, using technology similar to an optical mouse, with a red LED light located at the bottom of the controller. In order to move the Mag Kid across the screen during the game, the player must slide the entire Nintendo DS system with this ...
An additional risk is the (small) electrical conductivity of dust which, given enough accumulation of dust, can cause critical damage to the device's internal components. Dust accumulation grows exponentially, since the accumulated dust creates new static surfaces and physical blockades for new dust to cling to.
Iron powder has several uses; for example production of magnetic alloys and certain types of steels. [1] Iron powder is formed as a whole from several other iron particles. The particle sizes vary anywhere from 20-200 μm. The iron properties differ depending on the production method and history of a specific iron powder.
