Nokia Bell Labs is shy about its PatchKeeper device

Nokia Bell Labs has several exciting projects, including the PatchKeeper, a wearable biosensor designed to advance real-time health monitoring and diagnostics. This device features an Electronic Stethoscope (ES), PPG (photoplethysmography), ECG (electrocardiogram), and IMU (inertial measurement unit) sensors, making it highly adaptable across various applications.

It can be used for health monitoring in humans, animals, and even functional devices. The device weighs only 56 grams and measures 76x52x15 mm, making it lightweight and portable. It also includes Bluetooth Low Energy (BLE) for real-time streaming and a micro-SD card for offline data storage. The 400mAh rechargeable battery offers up to 20 hours of continuous recording and can be charged via USB-C.

The device’s applications include human health monitoring, such as tracking vital signals like abdominal sounds for digestive health influenced by stress. It can also be used for pet monitoring, with 24/7 activity tracking to study animal behavior, such as dog personality inference. Additionally, the device monitors internal sounds of home appliances or mechanical systems, assisting in predictive maintenance and performance optimization.

According to published scientific papers, this device is at least a year old, although the logo suggests it may be older. All in all, the PatchKeeper’s adaptability and precision make it a valuable tool in both healthcare and mechanical diagnostics.
