Currently, advanced artificial legs use transducers. Transducers are placed on the bottom of the artificial foot. They send electrical signals to electrodes on the user's skin. The electrodes are attached to a transducers which is in turn connected to the person's stump. |
|
To work, the stump picks up signals from the transducers and then transmit them to the brain just like a natural foot! The brain uses the messages to know the pressure on different parts of the sole. This means the wearer has a feeling of a real leg. This allows him or her to have more control over the leg. |
|
In the future, artificial limbs will allow more sense of feel to hands and feet. They will even be able to detect soft, rough, cold, and hot. |
