亮点原创 What would you like for lunch? Maybe, a battery? Although it sounds unusual, this has already been realized by scientists as they develop electronic things you can eat.
RoboFood, a programme led by Dario Floreano from the Swiss Federal Institute of Technology Lausanne, Switzerland, has been the trailblazer(先驱). Together with scientists from Wageningen University, the Netherlands, it has made a new drone. 1.
D
The programme also plans to create robots that can be eaten and foods that act like robots by mixing food science and robots in a new way.
According to the scientists, the wings of the drone were made from rice cakes glued together using oil and chocolate. Parts of the drone can be eaten since they meet food safety standards set up by the United Nations for emergencies.
2.
E
The materials for the drone's wings should be able to fight bad weather and high temperatures—of course, the chocolate may melt(融化) easily.
RoboFood also developed an edible(可食用的) sensor to help monitor(监控) stomach sickness. 3.
B
Unlike other sensors out there today, it's designed to be easily digested(消化), lowering the risk of leaving any remains inside the body.
4.
A
The world's first fully edible batteries can help address the growing problem of throwing away used batteries. The battery's anode(阳极) and cathode(阴极) are made of vitamin B2 and another natural element that can be found in many fruits including apples. 5.
C
A. The invention of such kind of food also helps with environmental protection.
B. It's eaten by the patient to check the conditions inside.
C. So the new battery can be more friendly to nature.
D. Half of the parts inside it can be eaten!
E. However, the main challenge is finding stronger edible materials.
