Infineon has introduced automotive microcontrollers with capacitive touch sensing for sensor and actuator applications. The PSOC 4 HVMS family is built around a 24 or 48MHz Arm Cortex-M0+ processor, with up to 128kbyte of flash and 8kbyte of ram. The ICs also have what Infineon calls ‘high-voltage’ capability for almost-direct connection to 12 and 24V vehicle batteries as they include an ...

Infineon has augmented touch sensing and liquid level sensing it a new series of MCUs. Devices in the 4000T family have hardware and software to implement: enhanced capacitive touch sensing, inductive touch sensing and capacitive liquid sensing. “Developers now have endless possibilities to develop new HMI and sensing solutions, from sleek metallic designs with touch-on-metal buttons, to waterproof touch-buttons and ...

Cornell Dubilier Electronics is aiming at harsh environments with a series of X2, EMI-RFI suppression capacitors. “The MXH series is AEC-Q200 qualified and has been temperature, humidity and bias (THB) life tested. “The 2,000-hour test conducted at 85°C, 85% relative humidity at rated voltage subjected these components to twice the standard test hours required to meet IEC 60834, Class III-B ...

ETH Zurich has created a yarn whose capacitance varies significantly with the movement of the textile it is woven into. The researchers “integrated it into a pair of athletic leggings”, according to the university. “Simply by glancing at their smartphone, testers were able to see when they were reaching their limit and if they ought to take a break.” This ...

Panasonic is to squeezed a single-pole normally-closed mosfet relay into a 1.95 x 1.8 x 0.8mm TSON package. An extension of the company’s CC series, “we are pretty certain that our 1FormB TSON type is currently matchless throughout the industry as far as size and current consumption are concerned”, said Panasonic’s Michael Renner. “With just an eighth of a SOP4 package’s ...

Schurter is aiming at easy-clean and sleek-looking surfaces with a ‘capacitive hidden switch’ that can be mounted behind thin non-conductive panel. Called the ‘CHS’ range, they come in three versions: non-illuminated, illuminated and sealed illuminated. They are mounted by gluing them to the back of the panel with pre-installed 3M 468MP tape. CHS 1 circuit – output is an open collector ...

  AMS has announced a configurable capacitive sensing front end which allows speed and resolution to be traded to optimise designs. Called PCap04, it can capture and digitise 50,000 times per second at its fastest setting, or achieve 8aF resolution at its most sensitive. “Configurability also enables sensor manufacturers to trade measurement speed off against power consumption. In low-power mode, ...

Atmel has found a way to add a force dimension to its touch screen chips without straying from capacitive measurement. The technology is sampling in its maXTouch U chip series for phones. “Force sensing expands the touch experience by bringing 3D interactions to enable users more intuitive control of their devices based on the pressure of their touch,” said the ...

Microchip has developed a capacitive contactless identification system that relies on near-field effects around the human body. A $1 fob or token, carried about a person, sets up a field that extends to the wearers fingertips, allowing them to prove they are the carrier by reaching their hand towards a reader. Branded BodyCom, no licence fees are payable providing it is ...

Microchip has increased the analogue capability of its 28pin 16F151x microcontrollers, with the introduction of the PIC16F1512 and 1513. There are now 17 inputs to the 10bit ADC, with hardware capacitive voltage divider support for implementing capacitive touch...
