A Balinese man, Wayan Sumardana, developed a self-made bionic arm in his workshop in the village of Nyuh Tebel in the Karangasem regency of Bali. The 31-year-old Indonesian welder known as 'Tawan' can move his arm with the device he was wearing. "There are electrodes attached to my scalp, whose functions are to take small signals from the head. These signals would not be detected without this device. The signal is brought forward to an enlarged signal and then taken to the micro-control in my back and transferred to the front,” said Tawan. "For example, I intend to move this part. Are all part of this activity, but depending on our needs. If the tool is not active, my hand silently sticks to the body. The process works like a dynamo; if there is a shortcut, it remains quiet but spends more energy," he added. Tawan suffered a mild stroke and the illness paralyzed his left hand six months ago.
