Justin Mullins although with the emergence of the computer, written text has made a great leap in recent years
Based on publishing and the global spread of text on the Web, humble pens are more or less the same equipment as ever.
Now, Philips, a consumer electronics company, says it has a breakthrough that can change the way we use pens forever.
Philips pointed out that the standard pen is not easy to do is to record the writer\'s mood in writing.
Therefore, it has developed a pen with a sensor to detect physiological factors such as heartbeat, blood pressure, skin temperature and finger pressure on its axis.
The pen also has a small actuator that can change the properties of the line tracked by the pen by switching ink and modifying the shape of the tip of the pen. A built-
The author\'s emotional state is then determined in chip and the color and quality of the traces are changed accordingly.
The result is a continuous recording of the user\'s feelings at the time of writing.
Philips said colon cancer.
\"Signatures are always the same at the moment, but some documents will be signed with enthusiasm and others may hesitate.
It may be useful to record this for historical reasons.
\"If you don\'t always want to reveal how you really feel, the company adds that the pen can have a button to turn off the effect.
Or you can use biro.

The compound eye of the fly has a unique optical structure and can see a view of up to 90 °.
In traditional optical systems, only fisheye lenses have a comparable field of view, but their internal lenses are complex and expensive.
Now, Luke Lee, a bioengineer at the University of California, Berkeley, has developed a way to create a tiny compound eye structure that is self-assembled.
The compound eye is formed by a large number of cells.
Just like the Tube that guides the light towards the sensor.
Lee first created a miniature honeycomb pattern.
By placing the droplets of the polymer on the sheet and allowing them to form the lens shape under their own surface tension, the lens is formed.
The hexagonal lens is then deformed into a dome shape.
The result is a tiny compound eye structure, which Li says may change completely.

Scientists regularly monitor the way our brains work in various cognitive tasks through functional magnetic resonance imaging (fMRI)
It reveals the areas of the brain that work the hardest.
In these tests, the researchers need to know where the subjects are, which usually requires the use of the eyes
Track the device that reflects the infrared beam from the eye to determine where it points.
It\'s expensive, it\'s hard to set up in the narrow range of the fMRI machine, and it\'s time consuming.
As a result, Hu Xiaoping and colleagues at Emory University in Atlanta, USA developed a software that can detect the orientation of the eyes with an fMRI scanner alone.
When the subject stared at the calibration target, the software learned to identify the eye direction from the fMRI data and then was able to calculate future eye movements by identifying the matching signals in the data.
