Microfluidic Cooling with Piezo Micropumps Dev Kit and PET Film

A Ready-to-Run Platform for Piezo Liquid Cooling Evaluation

The Microfluidic Cooling with Piezo Micropumps Dev Kit and PET Film is a ready-to-run evaluation platform for thermal engineers looking to validate piezo-driven liquid cooling before investing in a custom-designed sample. Two piezo micropumps circulate coolant through a flexible PET microchannel film, both driven by a single BOS1931 IC. Total power consumption across both pumps and the driver is less than 80 mW, with up to 6 W of heat dissipation. Connect via USB-C, launch Haptic Studio, and start collecting data.

The PET film is ultra-thin, flexible, silent, and transparent to RF signals, making it compatible with antenna designs in wireless consumer devices. Two piezo micropumps circulate liquid cooling through the film, both driven by a single BOS1931 IC on a controller board with a daughter card optimized for the micropump load.

Who Is This For?

This kit is designed for thermal engineers and system architects evaluating liquid cooling solutions for:

• Smartphones and mobile devices
• Wearables and hearables
• Fanless thin and light laptops
• Any compact, battery-powered electronics where heat management is a design constraint

It is the fastest path from concept to validated thermal data, without investing in a custom-designed sample.

Features

• Active Cooling at Minimal Power Cost:
  • Up to 6 W of heat dissipation: demonstrating real cooling capacity relevant to high-performance mobile SoCs and power-dense wearables.
  • Less than 80 mW total system power consumption: covering both piezo micropumps and the BOS1931 driver combined, making active liquid cooling viable in battery-powered products for the first time.
• A Film That Fits Where Other Solutions Cannot:
  • Ultra-thin and flexible PET microchannel film: can be routed around components and through tight form factors that rule out any rigid cooling solution.
  • Silent operation with no moving mechanical parts: the piezo micropumps generate no acoustic noise and no vibration, preserving the premium feel of the end product.
  • Transparent to RF signals: the PET film does not attenuate cellular, Wi-Fi, or Bluetooth signals, so antenna placement is unaffected by the cooling layer.
• Ready to Run on First Connection:
  • Plug and play via USB-C: connect the board, launch Haptic Studio, and start controlling the pumps and logging thermal data immediately, with no firmware development required.
  • Two piezo micropumps driven by a single BOS1931: one IC manages both pump channels simultaneously, validating a production-realistic architecture from day one.
• Validate Performance Before Committing to Custom Hardware:
  • Measure actual thermal performance on your geometry: generate real heat dissipation data on your target device before investing in a custom-designed PET film sample.
  • Compress the feasibility phase: go from first evaluation to validated results in days using a pre-integrated hardware and software stack.
  • Generate data your stakeholders can act on: produce concrete thermal performance numbers to support investment decisions and guide the next design phase.
