Abstract
The internal pressure pof the hollow body of a pneumatic structural element that comprises a hollow body (), at least two traction elements () and at least one compression member () can be electrothermally varied by means of a fluid. The hollow body () houses a void () which is filled with a gas (), and a container () which contains a volatile liquid (). Said liquid () can be heated or cooled by means of a heat pump (). Said heat pump () thermally contacts the liquid () via lamellas (). A pressure sensor () measures the pressure inside the void (). A cable () links the sensor () and the heat pump () with control and regulating electronics ().
