This Electrostatic Adhesion Plate Is Higher Than Magnets
In case you’re like most individuals, you in all probability stick your grocery record in your fridge utilizing magnets. As cool and versatile as magnets are, they’re previous information technologically talking. The recent new development that every one the children are into is electrostatic adhesion, and Jan Henrik has an open supply PCB design so that you may give it a attempt.
Electrostatic adhesion is identical pressure that makes your hair follow a celebration balloon whenever you rub it in your head. In that basic parlor trick, the static is constructed up by means of friction. However, static may also be created with excessive voltage electrical energy. Henrik’s design takes benefit of that reality to supply on-demand electro-adhesion that can be utilized to create a weak clamping pressure, however one that’s robust sufficient to carry up a bit of paper.
Henrik’s design is an easy and cheap PCB that’s constructed to deal with the very excessive voltages essential to create electro-adhesion, which is upwards of 500V DC. The again of the PCB has a Cockcroft-Walton voltage multiplier to generate that. The present is low, however there’s nonetheless clearly a number of potential hazard in the event you do it unsuitable, so watch out. Every PCB is 100 x 100 mm, however they’re designed in order that they are often soldered collectively to type a a lot bigger panel. If you wish to ditch the magnets and experiment with electro-adhesion, this can be a nice technique to do it!
