HealthyPi Move Packs Eight Biometric Measurements Into a Watch Form Factor

ProtoCentral designs and manufactures biometric measurement platforms. Their latest introduction is a watch form factor that does much more than just a traditional smartwatch. The HealthyPi Move precisely tracks eight vital signs and is entirely open source.

HealthyPi Move's face's diameter is 43 millimeters, and its body is 16 millimeters thick. The enclosure fits a 1.28-round TFT display with capacitive touch, a 150 milliamp-hour lithium polymer battery, and electronics. A Nordic Semiconductor nRF5340 system-on-chip (SoC) with dual-core Arm processor cores and Bluetooth radio running Zephyr powers HealthyPi Move and its sensors.

Previously, ProtoCentral brought HealthyPi 5 to market. It was the size of a Raspberry Pi and could work either stand-alone or as a HAT. The two products share some commonalities. For example, an Analog Devices MAX30001 performs ECG measurements.

The new HealthyPi Move is capable of measurements similar to HealthyPi 5 but in a small compact package. Five of HealthyPi Move's eight measurements are passive, while three require finger contact.

The HealthyPi Move measurements include these passive measurements:

• electrocardiogram (ECG)
• EDA/GSR
• heart rate variability (HRV)
• respiration rate
• body temperature

It can also measure these vitals with finger contact:

• blood pressure
• photoplethysmogram (PPG)
• SpO2

You can store measurements using the onboard 128 MB flash chip or stream them to a mobile device via Bluetooth Low Energy (BLE). This flexibility makes HealthyPi Move viable for research or tracking your vitals.

ProtoCentral plans to open source the EAGLE design files, software, and Fusion 360 design before shipping units. You can sign up on the HealthyPi Move campaign page to be notified when it goes live.
