Originally designed as a piezoelectric artificial muscle for our biomimetic cooling fans, our Python™ piezo bender addresses numerous issues found in conventional piezoelectric actuators, sensors and energy harvesters, giving it superior reliability and efficiency.
With Python™ technology the piezo layer is hermetically sandwiched between two durable epoxy resin layers. This sandwich-like structure is carefully engineered to give the piezo layer significant negative pre-stress. The Python™ bending actuator is further conformally coated with two thin silicone rubber layers to protect the piezo layer from humidity and condensation.
A superior piezoelectric bending actuator
The unique benefits of our biomimetic fans open up a range of new possibilities when approaching cooling requirements. Some industries with sophisticated cooling requirements include:
Soldering directly onto the piezo layer can cause cracks and failure due to thermal shock. That is why the Python™ bending actuator comes with thermally isolated solder pads to prevent this risk.
Similarly, clamping directly onto the brittle piezo layers may also cause cracks and failures. Therefore the Python™ piezo actuator includes passive extended portions at both ends. These parts can be drilled, machined, and clamped for mechanical integration without any impact on the actual piezo layers.
We are able to customize the form and shape of our piezo actuators for your specific needs, allowing them to fit multiple different applications.
