View gallery - 3 images Researchers at the Korea Advanced Institute of Science and Technology KAIST have developed a lightweight, flexible and high-efficiency thermoelectric generator that can harness your body heat to generate a small amount of electricity. The device could be used to extend the battery life of low-power wearable devices. The big names in personal electronics are constantly pushing for thinner and thinner devices, and while that certainly gives us much sleeker and attractive designs, it also invariably leads to compromises in terms of battery life. Previous attempts to generate additional power for personal electronics include solar-powered mobile phones and piezoelectric generators that create energy when pressed or bent the latter was also developed at KAIST.
Robot arms perform an incision during an ex-vivo test on a porcine gallbladder. The two arms, placing at the end of flexible endoscopes, highlight impeccable precision control and robust mini-joint design technologies. While cruising through the complicated inner body pliably, it carries out procedures on the spot with its robotic arms.
The research team under Professor Dong-Soo Kwon recently tested the device in-vivo, conducting a complicated endoscopic procedure dissecting a porcine gallbladder in collaboration with Professor Dae-Kyung Son of the National Cancer Center. The arms successfully manipulated the tissue safely.
During the test, K-FLEX, inserted through an incision in the navel, snaked through the narrow passages of the complicated inner organs.
When reaching the desired spot, one of the robot arms pushed aside and held up the nearby tissue to secure proper vision and space for the procedure. Keistc module8, a cautery needle mounted at the tip of the other hand removed the lesion tissue on Keistc module8 gallbladder.
The tiny camera installed at the front of the robot arms relayed the internal conditions. The full procedure was able to be monitored from the master console.
The two arms are placed onto 4. The arms can be deployable forward and backward and are extendable up to 7 cm for performing procedures. K-FLEX is made of domestically produced components, except for the endoscopic module.
It will expand new medical robotics research while offering novel therapeutic capabilities for endoscopes. Flexible endoscopes are very promising for surgical applications because they can treat areas thought to be difficult to reach, such as the posterior side of an organ.
Current rigid-type laparoscopic tools could not reach a lesion if it occurs in such serpentine and complicated areas. However, this flexible endoscopic surgery robot will bypass obstacles to reach the troubled area.
The ability to seamlessly integrate effective actuation into millimeter-scale deployable mechanisms fits well with minimally invasive surgical procedures. This flexible endoscopic surgery robot, only half the size of current laparoscopic surgical robots, is deployable into natural orifices such as the mouth, anus, and vagina without requiring external incisions.
Laparoscopic devices and robots require at least three to four external incisions to insert the devices; however, the applicability of internal incisions reduces the possibility of complications arousing from excessive bleeding and bacterial infections.
Despite these advantages, it has remained challenging to manipulate the robotic arms of flexible endoscopes with integrated grabbing force, flexibility, and multiple degrees of freedom for clinical environments.
The team focused on smaller but smarter devices. Min-Ho Hwang, a principal researcher of K-FLEX, said that developing tiny robots that are able to generate the necessary forces without compromising safety was the challenge.
They created a robust but smaller-joint technology that can exert a relatively greater force even into millimeter scale. We already confirmed the clinical adaptation through ex vivo tests and will see complete commercialization in two to three years.
