Actography (from Lat. Actus - action, movement, etc. Greek. Γράφω - I write) - a set of methods for recording movement in time.
It is carried out by special devices - actographers, in which the movement is transmitted to the sensors (in particular, rubber cylinders are used), and then converted into mechanical impulses acting on the recording device.
Application
The most widely used actography is to study the motor activity of animals during periods of sleep and wakefulness. In addition, actography is used to record movements during sleep or the movements of patients with bed rest.
Currently, mobile cells are used, suspended on a corrugated hose or on springs, with which they measure the displacement of the cell. The registration of human movements during sleep is usually carried out using pneumatic sensors placed in bed under a mattress or pillow.
