Get closer to Smart Baby Socks
Soft on the outside. A closer look within.
The familiar white-and-lavender knit stays at the heart of the product. Explore the compact pod and the principles behind foot-worn optical sensing.
02 / 02Product imagery is illustrative. Internal layers explain a possible architecture; they are not a teardown or a confirmed component layout.
Optical sensing
Light and a photodetector provide a route to pulse and oxygen-related signals.
Fit matters
Movement and sensor contact affect signal quality.
Connected information
Wireless transfer is part of the app-connectivity direction.
The technology, explained
From a small signal.
To a clearer picture.
An illustrative signal path for the connected product direction.
- 01
Illuminate
An optical module emits light at the sensing site.
- 02
Detect
A photodetector samples changes in returned light.
- 03
Assess
Algorithms must check signal quality and account for movement.
- 04
Present
Validated supported readings can be shown through the app.
Component options. Explained clearly.
Research candidates, not confirmed installed components. Final selection requires engineering, fit, power and product-specific validation.
Analog Devices MAX30102
Optical sensing
LEDs and a photodetector capture changes in reflected light. Pulse and oxygen-estimation algorithms need suitable placement, signal processing and product-specific validation.
Manufacturer specifications ↗Bosch BMI270
Movement sensing
An accelerometer and gyroscope measure acceleration and rotation. Software can use those samples to explore movement and posture trends.
Manufacturer specifications ↗Nordic nRF54L15
Processing + Bluetooth LE
A 128 MHz Arm Cortex-M33 processor combines local computation with a low-power radio. A candidate for collecting sensor samples and sending supported data to a companion device.
Manufacturer specifications ↗Component capabilities do not establish the finished product’s performance. Supplier comparison and component research reviewed November 2026.
