System Description

The SensFloor® system integrates a grid of capacitive sensor plates and microelectronic modules into a textile composite underlay by using a roll-to-roll manufacturing process that can be combined with the textile manufacturing process itself.

Key Terms in this Chapter

Embedded Receiver: Small devices that plug into a wall outlet and receive and process the sensor data from the SensFloor directly without the use of an external PC

Capacitive Proximity Sensors: Detectors which remotely measure the change of the electric field induced by objects or body parts

Position Estimation: Determining the position of an object based on either internal or external information

Trajectory: Movement path of walking people reconstructed from the sensor signals

Activity Monitoring: Continuously measuring behaviourally relevant parameters of people with the aim to detect changes of their state of health

SensFloor: Textile underlay with built-in wireless capacitive sensors for locating people indoor

Textile-Electronics-Integration: Mechanically embedding microelectronics into textile material and contacting it electrically

Ambient Assisted Living (AAL): Research field for evaluating technology and services to allow elderly or people in need of care to stay longer in their private homes instead of moving to nursery homes
