Here we’ll talk about the Hasel muscle used in soft robotics.
Physically this technology looks like one or more gel filled sandwhich bags with strings attached to some weight that it can lift when pressure is applied to the bag.
Hasel stands for the words “hydraulically artificial self healing electrostatic actuators”.
The inventor of the XRAY Wilhelm Genton(?) first made something that resembled a Hasel muscle.
