SPEC Sensors LLC

Tess Skyrme interviewed Ed Stetter, co-founder of SPEC sensors to discuss their business producing screen-printed electrochemical gas sensors, with primarily low-cost applications for OEMs in the safety, industry, air quality and health markets.

Printed electronics at CES

The 2014 Consumer Electronics Show finished a few days ago with an overload of media coverage and company press releases. Now that the dust has settled, we take a look back at some of the announcements that were made during the show and what they mean for Printed Electronics.

Learn about printed sensors at Printed Electronics USA

The 10th edition of Printed Electronics USA is only a few weeks away, and this year represents a unique opportunity to learn about printed, organic and flexible sensors.

KWJ Engineering Inc

In 2007, KWJ merged with Transducer Technology, Inc., adding the development of the next generation of nano-technology based sensors (electrochemical). KWJ's Screen Printed Electrochemical Sensor (SPEC) is a new generation of toxic gas sensor technology. The electrochemical device is based on current measurement (amperometric). SPEC sensors can be fabricated in very small sizes and require only microwatts of power for operation.

Printed sensors: an overview

There is an increasingly greater need for a wide choice of sensors to make objects smarter, safer and more responsive. Printing is the natural way to process wet inks and pastes, and it is therefore no surprise that printing has been used to make sensors for years. But there are new materials appearing, taking advantage of the progress that have been enabled by printed electronics. The article gives an overview of what is currently happening in the field of printed sensors. In particular, we will overview main trends in commercialising printed glucose sensors, force and pressure sensors, image and light sensors, gas sensors and temperature sensors. We will highlight key companies commercialising each printed sensor type.
