An improved miniature biosignal data sensor and recorder device is described, (NAT-1-4G)
with 3-axis accelerometer, and a 500 Sa/sec all-channel recording capacity of 36 hours or more with a single
zinc-air battery cell, and up to 6 days at 100 Sa/Sec for accelerometer only. Like the previous NAT-1 prototype
device, this measures less than 18×22×10 mm 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 itself has already achieved
translation to commercialization and is currently available
