Joint movement apparatus

A biological interface apparatus comprising:

• a sensor comprising a plurality of electrodes for detecting multicellular signals emanating from one or more living cells of a patient;
• a processing unit configured to receive the multicellular signals from the sensor, process the multicellular signals to produce a processed signal, and transmit the processed signal to a joint movement device;
• and
• the joint movement device configured to receive the processed signal and apply a force to one or more joints,
• wherein joint movement device data is transferred from the joint movement device to the processing unit.

A biological interface apparatus comprising:

• a first sensor comprising at least one electrode for detecting a first set of cellular signals;
• a second sensor comprising at least one electrode for detecting a second set of cellular signals that emanate from one or more nerves previously in neurological communication with a portion of a patient limb or a portion of a prosthetic limb replacing a patient limb;
• a processing unit configured to receive the first set of cellular signals from the first sensor, receive the second set of cellular signals from the second sensor, process the first set of cellular signals and the second set of cellular signals to produce processed signals, and transmit the processed signals to a joint movement device;
• a target limb comprising the patient limb or the prosthetic limb;
• and
• the joint movement device configured to receive the processed signals and apply a force to one or more joints of the target limb.
