Design and Applied Technology (Secondary 4-6)

2.3 NEW TECHNOLOGY

Due to the continuous research and development, scientists and engineers have kept giving

birth to new and emerging technologies over the last century. The emerging technologies

under the spotlight in recent years include nanotechnology, miniaturization, green

manufacturing and engineering. Such technologies, together with new materials, have been

applied to different manufacturing processes and, hence, have affected people’s daily life.

A typical recent example is iPhone. It consolidates the latest micro-chip, software, Internet,

wireless, miniaturization technologies into a palm-size device that enables multiple services,

such as telephony, email, SMS, television, data/ message upload/ download, business

transactions and entertainment.

2.3.1 Impact of new technologies on quality of life

Engineering and manufacturing produces by-products apart from their contributions to public.

For example, acid rain, greenhouse effect and disposal of damaging agents etc are still giving

a headache to society. These problems urge researchers for developing clean designs that can

enhance the positive impact on one hand and minimize the negative on the other.

It is already a problem to many big cities that the air quality is deteriorating in recent years.

Pollutants come mainly from power generation, automobiles and factories.
