At a time when the world’s economy is under tremendous pressure, there are few areas that are enjoying strong growth. One such area is the emerging field of printed electronics (PE). The idea is an intriguing one: by using low-cost printing processes to make certain electronic products such as RFID tags, solar cells, display screens, batteries and countless other applications, manufacturers can cut their costs and speed up production dramatically. Estimates as to the overall potential size of the market are as varied as they are large, with some figures reaching as high as $30 billion by 2015. These numbers have come down some in recent years, as there are hurdles to be overcome in each of these applications. However, there are plenty of companies, large and small alike, which are developing solutions for this field. The potential of this embryonic industry could be seen at Printed Electronics USA 2008, held last month in San Jose, CA. Accord
