Turn Any Smooth Surface into an Actuator, Buzzer, or Heater!

CoilPad is basically a Magnetic Sticker Actuator. It's just 0.1mm thin, flexible, and sticks to things. Flat or curved, just stick a CoilPad onto any smooth surface, add a magnet, and watch it swing. You can also hack it into the thin buzzer, micro-heater, or metal-detector!
The coil can be stuck on a curved surface, with an 18mm maximum bending radius. The adhesive used on the backside is 3M467. Its cover can be peeled off using a pair of tweezers. Always clean the surface before sticking the actuator, and it is very important to peel off the cover before powering on the coil; otherwise, the adhesive cover might get damaged.
This PCB is ROHS Compliant & follows IPC-A-600 II standard. Please note that the CoilPad is intended to be used as a DIY maker kit. For commercial purposes, please get in touch.

Full GuideCreative projects you can make with CoilPad:
Magnetic Surface Actuator
Flat or curved, stick it to anything smooth! Place a magnet near it to create motion
Kinetic Sign
Want to grab attention? Stick it to your message & go crazy with the frequency to catch some eyes!
Micro-Heater
Warm things up! It's round thin tiny area can safely heat up to 100ºC (212ºF) heating the surface
Origami
Use lightweight, flexible silicone-insulated wires to actuate your paper creatures to life!
Magnetic Buzzer
Bzzz! Add a magnet and drive it between 2kHz-16kHz ~ Turning it into an annoying buzzer!
LC Oscillator
Add a capacitor in parallel & drive it at its resonant frequency, to detal metal or power a wireless LED!
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.
