When a notebook becomes less than 10 mm thick, cooling becomes part of the product architecture. The attention around Lenovo’s Project AeroBlade concept reflects a practical question for electronics designers: how can increasingly compact devices sustain useful performance without making unacceptable compromises in temperature, space or noise?
In September 2026, Lenovo and Frore Systems introduced an AeroBlade proof of concept featuring Active Flow thermal technology powered by AirJet solid-state active cooling. Lenovo describes the 14-inch concept as less than 10 mm thick and less than 830 g in weight. PCWorld and Notebookcheck are among the publications that have covered the design. It remains a concept, but the thermal-design challenge it highlights is already relevant to product development.

Why micro cooling is attracting attention
Thin notebooks, portable storage and edge AI products face different workloads, yet their designers must all balance available space, temperature limits, acoustics and sustained performance. A brief demonstration does not establish how a device will behave through continuous operation.
MEMS micro fans and piezoelectric active-airflow devices create options for spaces where a conventional rotary fan is difficult to place. Public announcements from xMEMS address smart glasses and SSDs, while Frore has demonstrated solid-state cooling in thin computing devices. These are different implementations, rather than interchangeable products, but they show growing interest in bringing active airflow closer to local heat sources.
The benefit is more than a thinner component
A compact airflow device can give engineers another way to arrange cooling hardware around the board and surrounding components. High-frequency piezoelectric actuation and reduced dependence on rotating components also create opportunities for quieter designs. Airflow noise and enclosure coupling still need to be measured in the assembled device.
Local cooling is another attraction. A processor or storage controller presents a defined thermal target, allowing designers to evaluate airflow around a particular heat source. Some solid-state cooling products offer high back pressure for restrictive flow paths, while adjustable drive conditions can help match airflow to changing requirements.
The useful test is therefore the complete system: can it remove heat continuously, within the available space, power and acoustic limits? Component thickness and maximum pressure provide only part of that answer.
Introducing Semicera PiezoJeter
Semicera offers the PiezoJeter active piezoelectric cooling fan for compact-electronics applications. It uses high-frequency piezoelectric actuation to move air and remove heat through forced convection, without conventional rotating blades.
The designated Semicera product page lists a 30 × 45 mm footprint, 2.5 mm thickness, 1.4 W working power and cooling capacity of at least 5 W per module. These published specifications provide a starting point for selection; application performance depends on test conditions, heat coupling and integration.
Three exhibits connect piezoelectric materials with device applications
At CHInano 2026, Semicera is displaying PZT piezoelectric thin-film wafers, piezoelectric micromachined ultrasonic transducers (pMUTs), and the PiezoJeter active piezoelectric cooling fan. The exhibits connect materials, ultrasonic sensing and thermal management within a broader piezoelectric device-development conversation.
The PZT thin-film wafer exhibit features a high piezoelectric coefficient. For device developers, film properties must be considered alongside microfabrication, device structure and evaluation. Visitors can discuss their target applications and processing requirements with the team.

The PZT-based pMUT combines MEMS miniaturization with piezoelectric energy conversion. Its high sensitivity, low power consumption and integration-friendly design address ultrasonic sensing and imaging applications, illustrating a different functional use of the same wider piezoelectric technology portfolio.

PiezoJeter brings piezoelectric actuation to airflow and thermal management. Its compact structure and low-noise design direction make it a candidate for AI terminals, smartphones, notebooks, SSDs and power banks. Within larger AI server systems, evaluation should address a defined local component-cooling task rather than assume replacement of the entire thermal architecture.
Turning specifications into application discussions
For thin notebooks, evaluation may focus on installation height, sustained workloads and acoustics. Compact SSD assemblies can raise questions about local controller temperatures during continuous data transfer. Edge AI and mobile products require consideration of system power, available space and surface temperatures. PiezoJeter can be evaluated against these requirements rather than presented as a universal replacement for existing cooling architectures.
Semicera’s product page describes thermal simulation, airflow-path optimization and pressure-flow evaluation support. Sharing a defined heat load, target temperature, installation envelope and operating environment gives the technical discussion a useful starting point.
Meet Semicera at Booth 575 in Suzhou
Semicera is exhibiting at CHInano 2026, the 16th China International Nanotechnology Industry Expo, on October 21–23, 2026. Visit Booth 575 at Suzhou International Expo Centre to discuss PiezoJeter active piezoelectric cooling, PZT thin-film wafers and pMUT applications.
As thin design and sustained computing become simultaneous goals, thermal management needs to enter the design conversation early. Semicera welcomes discussions with device manufacturers, thermal engineers and development teams exploring where compact active cooling can add value.
