2 Product description
2.1 Function
The SensorHand Speed is a prosthetic hand with myoelectric control, featuring a particularly high
gripping speed combined with an innovative, sensitive control concept.
The SensorHand Speed is equipped with the SUVA sensors grip stabilisation system, the Flexi­
Grip function and a programming function. Proportional control with DMC (dynamic mode con­
trol) allows the patient to regulate the gripping speed and gripping force in proportion to the level
of the muscle signal. When the strength of the muscle signal changes, the gripping speed and
gripping force immediately adjust to the changed muscle signal.
The coaxial bushing of the 8E38=8* or 8E43=8 SensorHand Speed is marked with an orange
ring, and the connecting cable of the 8E39=8* SensorHand Speed is marked with an orange
sleeve.
Various control programmes make optimal adaptation to the individual needs and abilities pos­
sible.
SUVA sensors
The SUVA sensors integrated in the thumb (see fig. 1) recognise when a gripped object changes
its position and is therefore at risk of slipping out of the user's grasp. The system then increases
the gripping force automatically and continuously, starting from the originally specified initial grip­
ping force, until the object is in a stable position again.
FlexiGrip function
The FlexiGrip function allows a grasped object to be turned or shifted in the hand without having
to loosen the grip via electrode signals and subsequently re-grip the object.
The SensorHand Speed follows the changes in the position of the gripped objects like a natural
hand would. This makes the grip flexible.
The FlexiGrip function can be stopped at any time with a brief "OPEN" impulse.
