A Miniature Multisensor Biosignal Data Recorder and its Evaluation for Unsupervised Parkinson's Disease Data Collection

摘要

An improved miniature biosignal data sensor and recorder device is described, (NAT-1-4G) with 3-axis accelerometer, and a 2K Sa/sec all-channel recording capacity of 24 hours or more with a single zinc-air battery cell. Like the previous NAT-1 prototype device, this measures less than 18×22×10mm and weighs less than 2.3 grams, including the battery. In this paper we describe the device in detail, and introduce the presentation of tremor data measurement captured in the context of Parkinson's disease fore-arm monitoring. The NAT-1-4G device has already achieved translation to commercialization and we expect it to become commercially available in the near future.
