Microelectrode arrays printed on gelatin and other soft materials

On the one hand, the scientists around Prof. Bernhard Wolfrum did not print an image or lettering, but a microelectrode array. These components consist of a large number of electrodes and can measure changes in the electrical voltage in cells. These occur, for example, during the activity of nerve or muscle cells.

New touch technology generation enhances speed, accuracy and performance

The new controllers with custom design touch sensors can be manufactured to unique customer specifications without a minimum order quantity. The ZXY500 is suitable for displays from 5” to around 86” due to its 40V on-board drive signal and proprietary touch sensing algorithms. Noise immunity allows the air gap between the display and the sensor to be decreased, reducing optical parallax. Furthermore, the controller’s high SNR allows the touch sensor to be integrated alongside wireless technologies such as RFID / NFC readers and Qi chargers.

LCD touchscreen display modules for Raspberry Pi

The display modules offer either resistive or capacitive touch controls and are powered directly from the Raspberry Pi. Modules in the range come in three screen sizes – 4.3, 5.0 and 7.0 inch. The devices connect to the Raspberry Pi through a 30 pin FPC cable and an adapter board that conforms to the Raspberry Pi expansion header pin-out and Pi’s HAT device identification standard.

Rugged RS485 transceiver for extreme temperature or high noise environments

The device has enhanced overvoltage fault protection and extreme electrical overstress (EOS) protection that ensures reliable data communications in electrically noisy environments. The LTC2879X’s has a 3mm x 3mm footprint, which is 50% smaller than comparable devices.

The extreme temperature range, rugged fault tolerance, and low-drift, low-leakage circuitry of the LTC2879X device make it well suited for use in oil and gas exploration, industrial control, and aerospace and defence applications.

40V micromodule has failure mode compliant pinout

The pinout of the LTM8002 is FMEA (failure mode effects analysis) compliant, so in the event of short-circuit to GND, short-circuit to a neighbouring pin or if the pin is left floating, the output voltage safely stays at or below the regulated voltage. The µModule includes a switching regulator controller, power switches, inductor and other supporting components. Only the bulk input, output capacitors and two resistors are required to complete the design. 

Network emulation solution adds cellular IoT testing

The new TeraVM virtual Radio Access Network (vRAN) CIoT module can emulate over 16 million IoT devices via narrowband IoT (NB-IoT) and CAT-M connections in a fully virtualized environment. The new testing capabilities, says the company, lets operators, vendors, and service providers test and future-proof their networks for the development and commercialization of the Internet of Things (IoT).

AI creates realistic slow motion from standard video

Their approach, say the researchers, outperforms a variety of state-of-the-art methods aimed at doing the same thing. With it, users will be able to slow down their video recordings after taking them rather than have to engage a slow-motion video mode - typically 240 fps - while recording.

Algorithm compares 3D medical images up to 1000x faster

Medical image registration - the process of transforming different sets of data into one coordinate system - is a common technique that involves overlaying two images, such as magnetic resonance imaging (MRI) scans, to compare and analyze anatomical differences in great detail. For example, doctors can overlap a brain scan from several months ago onto a more recent scan to analyze small changes in a patient's brain, such as the progress of a tumor.

Fool's gold gives insight into potassium and sodium batteries

"One of the biggest obstacles for sodium- and potassium-ion batteries has been that they tend to decay and degrade faster and hold less energy than alternatives," said Matthew McDowell, an assistant professor in the George W. Woodruff School of Mechanical Engineering and the School of Materials Science and Engineering. "But we've found that's not always the case," he added.
