AUDIOWELL’s New-Generation Piezoelectric Air Pump to Debut at ICMD 2026

Piezoelectric Air Pump: Reshaping Micro-Fluid Drive with the Inverse Piezoelectric Effect

The piezoelectric air pump is an innovative achievement that deeply integrates precision electronic technology with fluid dynamics. Its core principle is based on the inverse piezoelectric effect of piezoelectric ceramics – when a piezoelectric ceramic material is subjected to an electric field, it produces mechanical deformation, converting electrical signals precisely into microscopic displacement. When a piezoelectric vibrator vibrates at high frequency under AC drive, it causes an elastic diaphragm to bend, resulting in rapid periodic volume changes of a sealed pump chamber. During chamber expansion, gas is drawn in; during compression, a high-pressure, high-velocity jet is formed through a tiny outlet, generating a continuous and stable airflow output.

Unlike traditional pumps that rely on motors and rotating parts, the piezoelectric air pump contains no motor, no bearings, and no rotating friction components. The drive source, transmission mechanism, and pump body are integrated into one, achieving extreme structural simplification and efficient energy conversion.

Three Product Features Directly Address Application Pain Points

Against the backdrop of medical devices rapidly evolving toward miniaturization, portability, and intelligence, the piezoelectric air pump demonstrates three significant advantages.

First, miniaturization and light weight. Through an integrated compact design, the piezoelectric air pump highly integrates the complex mechanical structure of traditional pumps, achieving dimensions as small as 21 mm × 19 mm × 3.2 mm and a weight of only 3.5 g. This characteristic perfectly matches the stringent size and weight requirements of wearable medical devices and portable diagnostic instruments – whether a wrist blood pressure monitor or a portable nebulizer, the piezoelectric air pump delivers stable and efficient gas drive within limited overall device space.

Second, flexibly adjustable output capability. The output air pressure and flow rate of the piezoelectric air pump can be flexibly controlled by adjusting the driving voltage – increasing the voltage raises air pressure and flow rate; decreasing the voltage lowers them accordingly. This adjustability allows device developers to freely match output parameters for different application scenarios and also offers end-users the possibility of personalized control.

Third, concentrated and efficient airflow output. Through a precisely designed tiny outlet, the piezoelectric air pump focuses and directs the high-pressure airflow, achieving high concentration and low energy loss. Measured data show that the product’s output pressure is ≥40 kPa (approximately 300 mmHg), and under a pressure load of 40 kPa, the gas flow still maintains positive output, demonstrating excellent load capacity and highefficiency gas delivery performance.

Deeply Engaged in the Medical Upstream Sector, Debuting at ICMD 2026

The 40th China International Medical Equipment Design & Manufacturing Technology Exhibition (ICMD) will be held grandly from April 9 to 12, 2026, at the National Exhibition and Convention Center (Shanghai). As a specialized exhibition under CMEF focusing on the upstream supply chain and manufacturing technologies for medical devices, ICMD concentrates on the entire industrial chain of medical device R&D, design, raw materials, key components, production technologies, and manufacturing. It brings together more than 800 upstream enterprises, showcasing core components and “AI + manufacturing” solutions to serve the innovation, development, and industrialization of medical devices.

As a high-tech enterprise with over 20 years of deep expertise in piezoelectric ceramics and sensing technology, AUDIOWELL is committed to driving innovation and breakthroughs in upstream medical device components with its core technologies. The newgeneration piezoelectric air pump exhibited this time not only inherits the technical essence of the inverse piezoelectric effect of piezoelectric ceramics but also achieves comprehensive upgrades in output performance, reliability, power consumption control, and other aspects. The product has a resonant frequency of 24 ± 2 kHz, operating in the ultrasonic frequency range with extremely low noise. Power consumption is only 1.5 W, and its electromechanical conversion efficiency is significantly better than that of traditional air pumps, achieving an excellent balance between precise control and low energy consumption.

Amid the wave of miniaturization, portability, and intelligence in medical devices, AUDIOWELL’s new-generation piezoelectric air pump – with its outstanding performance and significant application advantages – has already demonstrated broad application prospects in fields such as smart wearable blood pressure monitoring, micro-dose drug delivery, and negative pressure wound therapy.

In April 2026, AUDIOWELL sincerely invites medical device manufacturers, R&D institutions, and industry partners to visit the ICMD exhibition and jointly explore the further possibilities of microjet technology in the healthcare field.
