Tactile sensors for Humans and Robots
Ego tango, ergo sum.

The µGlove is a data glove that combines several complementary sensor modalities. In addition to a high-resolution measurement of the hand pose with 16 flex sensors, it records contact forces on the inside of the hand with 60 thin elastic cells. The tactile sensors operate in a spectrum from 0.02 N to > 50 N with a sampling rate of 1kHz. In addition, a position sensor records the orientation and acceleration of the hand. An optional tracking attachment allows the hand to be located absolutely in space.

With the µGlove, a comprehensive recording of human manual intelligence can thus be achieved, e.g. when intuitively handling everyday objects, as well as when interacting with other people. It is also possible to record and analyse favourable or unfavourable forms of movement during repetitive assembly work or in sports. Last but not least, haptic properties of objects can be intuitively captured and permanently stored for the first time, e.g. for use in a haptic VR.

Artificial-Skin is an approx. 1.5 mm thin and elastic tactile sensitive skin. The structure of technical textiles makes it both soft and robust and the sensitivity plays in the broad spectrum in which the forces usual for humans occur.

The signals are bundled via fine lines and then digitised.

Due to the properties of the tactile-sensitive cells, it is possible, for example, to sensitise the Shadow Robot Hands so that they can act and grasp more dexterously.

Unlike rigid foil-based sensors, artificial skin is particularly suitable for use in complex and moving structures such as those found in co.bots, humanoid robots or quadrupeds.
