Wearable Silent Blood Pressure Monitor Module
- World’s Smallest & Silent Blood Pressure Monitor Modules

DataSheets: Download

MicroJet Technology has designed the world’s smallest & silent blood pressure monitor modules B01AV for bracelet or smartwatch to built-in and works as a wearable blood pressure monitor. With our unique world-leading patented technology, people can monitor their blood pressure anywhere and anytime for your health. CurieJet®GS8D air micro pump is the only silent pump suitable for arm blood pressure monitors:

B01AV blood pressure monitor modules integrate our CurieJet® customized Air Pump, Pump Driving Circuits, Pressure sensor, Deflation Valve and Micro-controller. It uses air pump linear air inflation in the wrist-band cuff to pressurize arterial blood. It gets the oscillometric signal, Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP) and heart rate can be determined by oscillometric method from Microcontroller. All models have extremely tiny size and UART/IIC communication interface.

Developers may license our blood pressure monitoring algorithm firmware version -M1 oscillometric method, then to edit it by own enhanced blood pressure algorithm by firmware. There are different types option for A (Automatic deflation), M (Manual deflation), V (Vertical air outlet tube) and F (Flat air outlet tube). Current off-the-shelf model is B01AV; For B01AF, we shall discuss any medical approval necessity such as FDA. For B01MF, you may source air deflation valve for blood pressure monitoring, or other applications such as air bag massage (not allowing air leakage as power off).

Enhance the signal strength (PSNR& PI values) with PPG

CurieJet® blood pressure monitor modules also support unique patent to enhance the signal strength (PSNR& PI values) when in operation with PPG. It helps PPG module to fix tight to the skin.Below charts compare the application benefits.

With Micro-pump airbag (the PSNR&PI values are 11.12dB and 0.77%respectively)

Without Micro-pump airbag (the PSNR and PI values are 9.59dB and PI:0.41% respectively)

Evaluation Board

We can supply B01AV-E1 BP Evaluation Kit, a prototype of wearable blood pressure monitor, as B01AV EVM board on engineering sample watch. It includes B01AV, BLE Bluetooth, display and cuff working under Android APP.
