The innovative optical edge sensor PosCon 3D by Baumer is the most powerful in its class. It will reliably master tasks which previously required complex laser measuring systems. Additionally the PosCon 3D provides impressive convenience in both operation and installation. Multiple capabilities make the sensor a versatile solution to reliably detect edge positions and object […]
Human machine interfaces in wearable devices, remote controls, gaming devices, track pads and more frequently use projected-capacitive technology for touch sensing. In addition to glass front sensor construction for optics and light touch, projected capacitive technology has multi-touch capability that enables gestures and uses printed circuit board (PCB) sensor design to provide a cost-efficient touch […]
In this Frank Talk about Sensors, Randy Frank talks to Raymond Wiley, of SUN-Tec America, about the use lamination technology for improved touch sensor manufacturing. To hear the discussion, click here. For more information about SUN-Tec America, click here.
Using its Quantum Tunneling Composite (QTC) material, Peratech has developed a sensor design sensitive enough to detect the pressure of a finger on the top of a 0.1-mm stainless steel or 0.5-mm glass sheet. Mounted behind the sheet, the QTC material’s resistance changes when pressure is applied to the top of the sheet. The QTC […]
The Embedded System Conference was held in conjunction with Sensors Expo 2011 in Chicago. Rob Ostafia, Group Leader Curriculum Development at Microchip Technology explains the company’s products for capacitive touch sensing through several demo boards.

At Sensors Expo 2011, Randy Frank gets the scoop on the Industry’s first multi-touch controller for resistive touchscreens from Vijendra Kuroodi, principal systems architect at ROHM Semiconductor. With their ability to implement two-point operation and intuitive gesture control, the BU21023/BU21024 series is quite impressive. Since the controllers address resistive touch screens, they provide an alternative […]
At Convergence 2010 in Detroit Mich., Freescale Semiconductor’s Lydia Ziegler demonstrates how a software library controlled touch sensing can be used for slider and rotary switches in a vehicle’s center stack. The capacitive sensing uses simple metallic electrodes and the software completes the system. The software is an integral part of Freescale’s Xtrinsic touch sensing […]
At Convergence 2010, Atmel’s Toby Prescott demonstrates touch sensing in a remote keyless entry system. The capacitive touch sensing capability is provided by the ATA6617, a LIN system in package solution. Atmel’s QTouch Library enables a number of touch applications. Convergence has been the premier automotive electronics event since 1974. This year’s Convergence had a strong focus […]
Held in conjunction with Sensors Expo, I found an interesting sensor application in the exhibits at the 2010 Embedded Systems Conference Chicago. Cassandra Backus from Microchip Technology explained the company’s mTouch projected capacitive touch (PCT) screen sensing technology. With a higher resolution than resistive technology, the PCT approach has found its way into many of […]
