· The MEMS piezoelectric pump is a revolutionary product of micropump
manufacturing technology. It uses the inverse piezoelectric effect of
piezoelectric ceramics to deform the piezoelectric vibrator, which in
turn causes volume changes of pump chamber to achieve fluid
transportation.
· MEMS piezoelectric pumps have the characteristics of extremely small
size, high integration, low power consumption, high specific flow rate,
and high specific back pressure. They have unique advantages and can be
applied in the fields of microfluidics, medical devices, and
semiconductor thermal management, especially suitable for integrated
applications of microsystems.
The BP Monitor Solution consists of a MEMS piezoelectric pump, a
variable modulus tactile sensing wrist cuff, a high-modulus and highly
flexible fiber watchband, and a highly precise and generalized AI BP
algorithm. In principle, it uses the oscillometric boosting method and
has more faster and more accurate blood pressure monitoring. Key
innovations include:
1) By using MEMS pump-valve integrated devices as an inflation source
and control valve, it significantly reduces the size of conventional
blood pressure monitors, enabling the integration of blood pressure
measurement into a typical wristwatch-sized device.
2) For achieving further accuracy improvement, use multi-sensors to
collect raw data. Pulse wave is sampled bymulti-layered spring-type
tactile sensing wrist cuff, air pressure and contact pressure are
collected by dual data curve simultaneously.
3) To solve the specificity of narrow balloon sensing component, AI BP
algorithm is used to achieve non-linear correction of wrist cuff
pressure and artery pressure. It has strong population adaptability
and universality, and can be updated by OTA.
