Micro Piezoelectric Pumps: A "Magic Tool" for Wearable Devices Crossing into Healthcare

Background and Industry Opportunities

In 2023, the Hypertension Prevention and Treatment Guidelines officially included wearable devices in the processes for blood pressure measurement and hypertension diagnosis. This policy has driven the development of high-precision "wrist blood pressure monitors", creating significant opportunities for wearable technology to cross over into healthcare.

To achieve internationally compliant blood pressure measurements, wearable devices have widely adopted a micro pump + airbag structure, with the micro piezoelectric pump emerging as a core technology.

What is a Micro Piezoelectric Pump?

Definition: A high-precision fluid control pump based on microfluidic technology.

Key Advantages: 

- High back pressure, large flow rate
- Miniaturization, low energy consumption
- High precision, rapid response
- Ultrasonic-driven, low noise (<40dB), no electromagnetic interference
- Low driving voltage with precisely controllable flow and air pressure
