Abstract—In this paper, we describe a miniature biosignal data
sensor and recorder device, (NAT-1) with 3-axis accelerometer,
and a 2KSa/sec all-channel recording capacity of 24 hours or
more with a single zinc-air battery cell. The device measures
less than 18x22mm and weighs less than 2.3 grams, including
the battery. The device is evaluated in several contexts,
including electroencephalography data collection, forearm
electromyography capture, and in use as an accelerometer for
movement capture in sport. We describe the device, its use,
and show examples of some monitoring applications; in all
cases, data is collected in an untethered stand-alone mode. The
NAT-1 has already achieved translation to commercialization
and is the first of a new family of sensors.
