Electronic sensors built into paper could be used in a range of ways from information storage to touch screens and more.
Electronic sensors built into cartons（纸盒）may make it easier to tell when it’s time to throw out rotten milk or orange juice. And that’s just the start. At least that’s the goal for researchers working on putting electronics into paper. They’re trying to figure out how to combine the flexibility, low-cost and recyclability of paper with the information-carrying ability of electronics.
Daniel Torbjork, a physics graduate student in Finland, has been working on the problem. He’s published a review of the field in the journal Advanced Materials.
Much research has been focused in this area. While most electronic applications require patterned conducting structures, conductive paper could be used in applications such as energy storage devices, sensors, electric heaters and others, according to Torbjork.
“You could even have some interactive functions in magazines,” Torbjork said, “You could put a simple game in a package. If you want a touch screen, press a button and then something happen. Sensors in paper could tell us when something has gone bad.”
Additional applications, such as information storage and security paper, have been suggested for magnetic papers containing magnetite. In Massachusetts, researchers have figured out how to post a video of such a device put into a paper airplane.
German researchers have also put electronic chips in paper bank notes to defend counter-feiters（造伪币者）. Paper is a good material but printing electronics also requires low-cost manufacturing. As many US and European paper makers lose market share to cheaper paper from China, these big paper companies are looking for added value products. That’s where electronic paper devices could make a difference.
“The major obstacles are paper’s large surface roughness and chemical impurities.” Torbjork says. But others in the field think that electronic sensors in paper are still far from the consumer marketplace.
“I don’t think it’s going to happen.” said Roy Horgan. “You need a conductive surface. It could be 10 years out. What we are looking for are solutions that you can commercialize today.”
Solar Print is partnering with Italian automaker Fiat to develop a unique auto-glass with tiny photostatic cells（光电）that can capture electricity from the sun. In the meantime, using paper to conduct electricity is still a “blue-sky” project.
“I would love to see someone prove me wrong, because that means that it’s actually happening.” Horgan said. “If someone comes up with conductive paper, then that’s a very interesting technology.”

Biologists believe that love is fundamentally a biological rather than a cultural construct, because the capacity for love is found in all human cultures and similar behavior is found in some other animals. In humans the purpose of all the desire is to focus attention on the raising of offspring. Children demand an unusual amount of parenting, and two parents are better than one. Love is a signal that both partners are committed, and makes it more likely that this commitment will continue as long as necessary for children to reach independence. But what does science have to say about the notion of love at first sight?
In recent years the ability to watch the brain in action has offered a wealth of insight into the mechanics of love. Researchers have shown that when a person falls in love, a dozen different part of brain work together to release chemicals that trigger feelings of euphoria, bonding and excitement. It has also been shown that the unconditional love between a mother and a child is associated with activity in different regions of the brain from those associated with pair-bonding love.
Passionate love is rooted in the reward circuitry of the brain—the same area that is active when humans feel a rush from cocaine. In fact, the desire, motivations and withdrawals involved in love have a great deal in common with addiction. Its most intense forms tend to be associated with the early stages of a relationship, which then give way to
a calmer attachment form of love one feels with a long term partner.
What all this means is that one special person can become chemically rewarding to the brain of another. Love at first sight, then, is only possible if the mechanism for generating long-term attachment can be triggered quickly. There are signs that it can be. One line of evidence is that people are able to decide within a second how attractive they find another person. This decision appears to be related to facial attractiveness, although men may favor women with waist-to-hip ratio of 0.7, no matter what their overall weight is. (This ratio may indicate a woman’s reproductive health.)
Another piece of evidence comes from work by a psychologist at Ben-Gurion University, who found in a survey that a small percentage (11%) of people in long-term relationships said that they began with love at first sight. In other words, in some couples the initial favorable impressions of attractiveness triggered love which sustained a lengthy bond. It is also clear that some couples need to form their bonds over a longer period, and popular culture tells many tales of friends who become lovers.
One might also assume that if a person is looking for a partner with traits that cannot be quantified instantly, such as compassion, intellect or a good sense of humor, then it would be hard to form a relationship on the basis of love at first sight. Those more concerned with visual appearances, though, might find this easier. So it appears that love at first sight exists, but is not a very common basis for long-term relationships.
