The NAT project is now moving into a commercialisation phase, some details are therefore considered too sensitive to report in the public domain at present on these pages.
NAT (Neural Activity Tracker) is a miniature device, no larger than a 2p coin, and weighing only a few grams. The device is designed to record neural activity and 3-axis accelerometer data from a subject under test (a clinical patient for example). We expect the device to be able to act as a wearable sensor for EEG, EMG, and tremor (e.g. Parkinson's Disease symptoms) and activity sensing.
The Current device is capable of recording data at high speed over 24 hours, and over considerably longer periods with lower sample rates.
Coupling the sensor hardware with the group's specialised Signal Data explorer software toolset (SDE - also a commercial product) allows an advanced signal acquisition and interpretation system to be built for a number of potential end-use scenarios.
