The SOMNOtouch PSG is an 84 x 55 x 18 mm (slightly larger than a credit card) American Academy of Sleep Medicine compliant polysomnography (PSG) device.

It includes a home sleep camera, which is a solution for synchronous video in an ambulatory setting. It is especially useful in scenarios when reimbursement requires a video, such as for pediatric or adult ambulatory polysomnography, and works in areas incompatible with online recording due to network or location restrictions.

Real-time data is displayed on the high-resolution touch screen. The measurement data can also be transferred to tablet and smartphone for a signal check.

It is 64g, including the battery. Integrated sensors and the built-in Li-Ion battery keep the running costs per measurement low.

The headbox for ambulatory sleep staging records 4 EEG, 2 EOG, and 1 EMG. In addition, combination sensors can be used to record PLM and ECG in order to complete the signals required for polysomnography.
