How can you secure a sensing node?
At Sensors Expo 2018 in San Jose, CA, Martin Squibbs, Product Marketing Manager for Microchip Technology discusses the company’s newest SAM L11 microcontroller (MCU), the first on the market to have the Arm Cortex-M23 core with TrustZone. Leveraging TrustZone, the three differentiating features of the 32-bit MCU are high security, parallel capture (through a two-stage […]
How can smart phone type touch sensing be implemented in a home control unit?
At CES 2017, Tobias Eichenwald, Co-founder and CEO of Senic GmbH, demonstrates a smart home control button that mimics smart phone type touch sensing. In a programmable interface, the touch sensing provides buttons, an analog ring for variable control, touch surface for browsing, and swipe as well as proximity sensing without touch for music, lighting […]
Process lets sensors be applied by machine
Until now, plastic parts have predominantly been manually equipped with sensors using mainly the expensive OCA (optically clear adhesives) technology. Integration processes developed by Kurz, however, enable sensors to be applied very quickly and economically by machine. The sensors, including electrical connection (tail), are permanently bonded to the component and are immediately functional. This has […]
Wearable System Tracks Skin Touch
Developed by the Future Interfaces Group (FIG), a research lab at Carnegie Mellon University, SkinTrack is a wearable system that tracks skin touch to interface with a host. The system consists of a ring and a sensing wristband with multiple electrodes. The ring emits a continuous high frequency AC signal and based on the inherent […]
Laser Sensing Technique Enables Projected Touch Screen
The touchscreen of smartphones and tablets is a must have for these devices. Now, a touchscreen is available on any projected surface thanks to the addition of a laser beam. Easitech’s Lazertouch system sends an invisible laser beam in parallel with the projected visual information. When the finger touch laser beam sensor detects a finger, […]
Press-fit reed sensors designed for 9.5-mm-dia. holes
Littelfuse, Inc. has introduced the 59040 Series press-fit reed sensor, the first Firecracker reed sensor from Littelfuse with crush ribs on the capsule that requires no attachment accessories for installation. This magnetically operated sensor is designed to press-fit securely into a 3/8” (9.5mm) diameter hole and offers another sensor option for the competitive reed sensor […]
First large area fingerprint and vein sensor on plastic
FlexEnable and ISORG have revealed the world’s first large area flexible fingerprint sensor on plastic designed for biometric applications. With an 8.6 cm x 8.6 cm active area, 84µm pitch (78µm pixel size with 6µm spacing) and 1024 x 1024 = 1048576 pixel resolution, this revolutionary flexible sensor is only 0.3 mm thick and can […]
Implement Proximity and Touch Sensing Technology without Writing any Software
Replacing a mechanical switch with a digital output touch sensor is a lot easier if the system designer does not have to write any code. With that goal in mind, Microchip Technology developed its MTCH102-5-8 capacitive touch controllers. The 2-, 5- and 8-channel controllers replace mechanical buttons with a simple digital output in a hardware-only […]
A New Touch Sensor Option
Traditional touch sensors technologies include capacitive, resistive, infrared touch and surface acoustic wave. However, moisture, changes in surface temperature or materials or other surface variations can prevent these sensors from detecting the proper pre-determined threshold to trigger a touch event. For example, capacitive touch technology in a cell phone can be ineffective when your finger […]
