A team of engineers has developed an adhesive sticker for the back of the neck that integrates a piezoelectric mini-fan only half a millimeter thick. The device vibrates at high frequency to generate micro air currents, eliminating the need for traditional blades or motors. This concept promises to discreetly and silently relieve heat.
How piezoelectric technology works without moving parts 🌀
The system is based on a piezoelectric material that deforms when receiving an electric current. This vibration, imperceptible to the touch, pushes the surrounding air, creating a continuous flow over the skin. With no rotors or propellers, mechanical wear is practically zero. The 0.5 mm thickness allows the sticker to adapt to the curvature of the neck without bulging under clothing. Power comes from a flexible micro-battery attached to the same patch.
Now you can sweat in style without anyone noticing 😎
Finally, a solution for those moments when your neck is burning but you don't want to look like a walking appliance. The sticker is so thin that your boss will think you're wearing a patch for neck tension, not a state-of-the-art fan. The downside: if the system fails, you'll have to explain why you have a tech gum stuck to the back of your neck. And no, it doesn't work for repelling mosquitoes.
