How the non-stretchable flexible PCB can stretch
Stretchable LED lamp wrapped around a tube using a Tomoe type structure.In response to the increased demand for wearable devices and dynamic applications, several methods for expanding and bending flex PCBs have been proposed in recent years.Our solution is a stretchable circuit board that uses a Tomoe-type structure.Although the materials of the flex PCB do not stretch, it is possible to stretch a circuit board by giving it a Tomoe-type structure.Taking the example of the figure below, when ...

Stretchable biological electrodes
Although the materials of the flexible PCB aren’t expandable, we have succeeded in realizing a stretchable PCB by combining laser cutters and papercutting (kirie) techniques.(Developed Product) Picture: Working sample of an EMG with Ag/AgCl electrodes fixed as supporters without any need for gel.Biomedical electrodes that can stretch according to the various forms of the body are needed to measure ECG, EEG and EMG. At Elephantech, we have succeeded in achieving a stretchable circuit board typ...

Tomoe type kirigami structure for 180˚ bends
Flexible PCBs are generally known for being thin and easily bendable. However, from the perspective of minimum bend radius and flex resistance, there was a risk of breakage due to repetitive or excessive bending.By using a Tomoe type kirigami structure as shown in the figure, the wiring can be bent 180˚ without creasing the wiring.(*)The Tomoe type cut pattern allows a movement of 180˚ without folding or leaving a crease.The lack of creases reduces the risk of breakage, and it can be applied ...

Electrochemical sensor
We are developing application products that use flex PCB.An electrochemical sensor is a sensor that can figure out the status by using redox potential. for environmental and water quality analyses, measurement of the amount of copper, arsenic, and mercury and the like contained in the water.for measurement of the blood glucose level, lactic acid, urine sugar sensor, and glutamic acid etc as a transducer part of a biosensor etc...Usually, the electrochemical sensor is manufactured only by silk...
