Researchers from Asia and Europe have developed the world’s lightest and thinnest organic circuits, which in the future could be used in a range of healthcare applications.
Lighter than a feather, these ultrathin film-like organic transistor integrated circuits are being developed by a research group led by Professor Takao Someya and Associate Professor Tsuyoshi Sekitani of the University of Tokyo, who run an Exploratory Research for Advanced Technology (ERATO) program sponsored by the Japan Science and Technology Agency (JST), in collaboration with Siegfried Bauer’s group at the Johannes Kepler University (JKU) Linz, Austria.
The circuits are extremely lightweight, flexible, durable and thin, and conform to any surface. They are just 2 microns thick, just 1/5 that of kitchen wrap, and weighing only 3g/m^2, are 30 times lighter than office paper. They also feature a bend radius of 5 microns, meaning they can be scrunched up into a ball, without breaking. Due to these properties the researchers have dubbed them “imperceptible electronics”, which can be placed on any surface and even worn without restricting the users movement.
There is a circular hole in the wall, about 30-40 cm diameter and perforated at 1 meter above the ground. A man enters through the hole in the wall and a man (apparently the same individual) exits again through the same hole. His mate is standing right next to the hole and seems to be waiting for him. Yesterday I came across these pictures again. The enigmatic hole is the entrance to a room. It is a door that keeps you fit, elastic and flexible, if you want to discover what there is at the other side of the wall. Its dimension relies on the utmost reduction of a bending human body. And the erotic experience of penetrating it is intimately connected both to the materiality of the hole and the earthen texture of the wall. It is an intuitive understanding of a house as the shelter of a woman’s uterus. It requires thinking where to place first a leg, an arm, then a hand and a foot. But even if it looks like a perforation, as if material had been removed out of the massive surface, the hole was indeed already there before the wall was built all around it. It is incredibly mysterious when our iconic idea of a rectangular door mutates and becomes something else that defines a new type of threshold.
Below there is another door of Korongo houses that also fascinates me: the oversized threshold, shaped as a human-size keyhole. One discovers its meaningfulness after knowing that it lets villagers access the room while carrying two large jars with drinking water hanging from a stick over their shoulders.
George Rodger captured in his photographs the everyday lives of the Nuba people in Sudan in late 1940s, their houses, their wrestling combats with sharp-edge bracelets, and their aesthetic scars that adorn their bodies.
