Piezoresistive Sensors - Part 1 of 3

In the first of this three part series on piezoresistive sensors we look at the construction, manufacture and types of pressure and force sensors and the key players in these fields. In subsequent articles, we will investigate the applications and then emerging technologies in this space.

he company was established in 1996 to exploit QTC™ (quantum tunnelling composite) materials and now has worldwide patents for QTC™ Materials.

The future of printed piezoresistive sensors

Sensing is an increasingly important application in printed electronics, partly because printed sensors can enable new ways to interact with machines and smart devices. In this article, IDTechEx takes a closer look at a well-established printed sensor technology: printed piezoresistive sensors.

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.

Peratech creates fast-acting Electronic Nose using QTC technology

QTC™ materials change their resistance when a force is applied and, in this case, the polymer content of the composite swells when exposed to VOCs.

Printed Electronics at Peratech

Peratech is offering a novel and interesting ink that can change its resistance by as much as 16 orders of magnitude when pressed with a finger!

Growth in printed electronics

Last week IDTechEx held the largest (worldwide) printed electronics and photovoltaics conference and tradeshow in Silicon Valley (Santa Clara Convention Center, California). This show brought together more than 1300 attendees from 28 countries. Players active across the entire value chain were present; covering the full range from research organisations to end-users, and from small start-ups to multi-billion internationals.

IDTechEx Printed Electronics USA 2011 award winners

The annual printed electronics award winners were announced at the IDTechEx Awards Dinner in Santa Clara, California. The awards recognize outstanding progress in the development and commercialization of printed electronics, an industry that produces a huge amount of technical innovation which will be used in many products.

Peratech's new, see through QTC Clear will revolutionise touch screens

Peratech, the innovators in touch technology, have developed a see through version of their award winning, Quantum Tunneling Composite (QTC™) material called QTC Clear™. This force sensing material can be used to create a whole new class of Force Sensitive touch screens that can completely replace current Resistive touch screen technologies or enhance Capacitive ones to create superior solutions with more features such as 3D input.

Printed electronics - Europe is different

Printed electronics is one of the most important new enabling technologies.
