Electric Gum: Scientists at Meiji University in Japan have
developed a special device named electric gum’ which brings individuals the
sensation of a chewing gum that never loses its flavour. Although the device
zaps one’s tongue to stimulate taste, the process is completely painless.
Behind the electric gum is the piezoelectric effect. This is a phenomenon
during which the squeeze of certain materials can produce an electric
charge. Currently, the electric gum is able to stimulate bitter and salty
tastes but there is a plan to further develop the product in accordance with
Paper Wristband Saves from UV- rays: A paper wristband has been
developed by a team of researchers at the RMIT University in Australia and
the University of Granada in Spain. The wristband features specialised
phosphomolybdic ink on the exposed portion. The ink will change from
colourless to blue once exposed to UV light and with transparent film layers
over some portions to make it harder for rays to permeate. This helps
wearers of the paper wristband quickly identify when they have gotten their
limit of the sun to remind them when it’s time to head indoors.
Sun exposure is healthy and essential but too much can lead to skin
damage and cancer, so this paper wristband has been developed as a
cost-effective solution to help wearers know when they should seek coverage.
Microscopic Optical Gyroscopes: The Company Caltech developed a
gyroscope significantly smaller, as the size of a grain of rice. Gyroscope
devices are generally used to measure or maintain orientation and angular
velocity and are used in everything from mechanical systems to smartphones.
Innovative Cooling Technology: Researchers at Stanford University
have developed a new type of solar panel technology that can replace bulky
and energy-hogging air conditioners to combat climate change. This new
cooling technology takes the heat generated from the sun with the help of
solar panels and converts it into electricity and also releases an excess of
heat into space. The process needs less energy than traditional air
conditioners and keeps buildings cool and comfortable. The cooling
technology is still currently in development but can help solve the greater
issues of climate change.
