Bend it, stick it, and make it move with magnets! The CoilPad is an ultra-thin, flexible planar coil actuator that seamlessly sticks to any smooth surface, that lets you experiment with magnetism and create compact magnetic actuators! It can be used for magnetic motion, buzzing, heating, or even metal detection.
By simply adding a magnet, the CoilPad converts electrical energy into mechanical movement. When an electric current flows through its coil, it generates a magnetic field that interacts with the magnet, creating a controlled motion. Alternating the current’s direction allows for actuation, while a square wave signal enables continuous oscillation.
CoilPad can attract and repel magnets by generating a magnetic field. However, the field it creates is much weaker than the magnetic field of a magnet. As a result, the forces generated are primarily due to the magnet. Unfortunately, this means two CoilPads cannot attract or repel each other.
Want to make a CoilPad flap or vibrate with magnets? To achieve this, you'll need transistors like an H-Bridge to flip its polarity and adjust its position. That’s why we highly recommend our compact DriveCell module, measuring just 0.8 cm wide! It can deliver up to 1.8A, giving you the power to control up to 8 CoilPads with a single DriveCell!
CoilPad is ideal for anyone interested in exploring electronics! For younger users, we recommend adult supervision and guidance, as CoilPad requires soldering and can heat up to 100°C during use. To prevent injury, keep hands away from hot surfaces and always turn off the coil when not in use. Please note that the package contains small parts, such as magnet, which should be handled with care.
This depends on the magnet you're using and the actuation distance you're trying to achieve, but it typically peaks at 25Hz.
