The haptic glove he uses to control the robotic hand includes: 

5 homemade flex sensors - made out of aluminum and copper wiring 

one nRF24L01 transceiver

an arduino nano 

a range of different resistors (he gets into the details in the video)

a 5v and ground rail copper connection wires

for the robotic hand's material, he chose to go with balsa wood. he starts out by cutting out proportions copied from his own hands, then used hinges to connect the pieces together. to get the hand to bend correctly, he used a kind of flexible string found on amazon. He then set up 5 servo motors to all 5 fingers via string on the palm of the robotic hand, which were controlled via arduino uno + transceiver #2.
