The Danish developed Kataka or ‘golden chain’ actuator, revealed in the October 2003 edition of Eureka, has now been developed into a form that is capable of being used as a car jack
 .
The device is made up of links, which sit in a rectangular guide until they are drawn forth and formed into a spiral rod that extends from one end at 90º to the axis of the guide.
According to CEO Søren Søgard Jensen, the first commercial products can support a load of 200kg for 20,000 cycles. The units are 50mm x 125mm wide x 380mm long and have a stroke length of 400mm. The actuators can be attached to mechanisms using M8x8 threads on all six sides of the units.
The first commercial applications will be in wheel chairs, embedded in a scissor lift for ‘height adjustable kitchens’ and for tilting ‘comfort seats’.
Other applications are seen in white goods, home automation products, robotics, consumer electronics, automotive and aerospace.
