Sensors, Haptics & Displays

As more and more flexible devices are becoming available, the need for better performing barriers and encapsulation materials at lower cost points intensifies.

Although thermoelectric phenomena have been used for heating and cooling applications quite extensively, electricity generation has only seen very limited market in niche applications and it is only in recent years that interest has increased regarding new applications of energy generation through thermoelectric harvesting.

Energy harvesters and wireless sensors are not always deployed under "a walk in the park" operating environments. If anything, the most interesting applications for these technologies tend to be in sectors where conditions are harsh or devices are inaccessible once deployed.

Today, only one type of film - Indium Tin Oxide (ITO) - is used for almost all transparent conductive films with a market size of over $2 billion this year.

Recently IDTechEx attended the solid-state lighting workshop in San Jose, California.

There have been three billion-dollar success stories in printed and organic electronics so far - and in each Asia has been a key driving factor.

Conductive inks are a simple and unglamorous layer but they will constitute a hefty $2.86 billion market in 2012.

These naturally occurring, but mostly manufactured, piezoelectric materials are fast becoming a hot topic for exploration in energy harvesting, exhibiting 10 times as much voltage output compared with polycrystalline PZT(1) are utilized in applications where the emphasis is on high output and sensitivity.

Starting with more humble killer applications such as meter reading in buildings, WSN will grow rapidly from $0.58 billion in 2012 to $2.4 billion in 2022 according to IDTechEx research.

IDTechEx recently visited South Korea as part of a UK Trade and Investment mission. Here we summarise some highlights of the trip.
