BOE under-display TFT Fingerprint sensor with Guillaume Chansin Irimitech

Posted by Charbax – July 11, 2018

BOE shows their new under-display fingerprint sensor at SID Display Week 2018. It is an optical sensor with a resolution of 500 dpi placed directly under an OLED display based on TFT circuitry that has been certified to meet the TEE standard. Other companies like Synaptics have shown similar concepts before, but this is the first time the under-display fingerprint sensor is made with TFT. Dr Guillaume Chansin who is a consultant in sensor technology at Irimitech gets a hands-on demo. He says there are advantages in using TFT instead of CMOS to make a large sensor that could potentially be the same size as the display in the future. According to BOE the sensor material is not silicon so it is cheaper to manufacture. They can make the sensor on glass or on flexible plastic (for matching with flexible OLED displays).

Holst Centre IMEC fingerprint sensor in display, organic photodiode frontplane, IGZO backplane

Posted by Charbax – June 22, 2018

Holst Centre demonstrated next-gen technology that integrates the fingerprint sensor into the display. Using flat-panel display (FPD) compatible processes, Holst Centre researchers created a 6x8-cm, 200 ppi active matrix imager with a solution-processed, ultrathin organic photodiode frontplane and an IGZOTFT backplane. The imager was demonstrated in a biometric palm print and multiple-finger detector. They believe the palm print is a more secure biometric than fingerprint scanning; and the processing of all building blocks in the palm print imager is compatible with existing FPD technology platform.

BeBop Sensors, Smart Glove sensing with haptics, Drum Pad at CES 2018

Posted by Charbax – January 25, 2018

BeBop makes fabric sensors that are piezo-resistive, they showed off their latest product the Forte Wireless Glove that can sense finger movements and incorporates haptic feedback. Ideally used in VR applications, this glove can work for 15 hours on a single charge, it is a one size fits all model, very fast response up to 150 frames/second for gaming applications, unique haptic actuators embedded at each finger tip. BeBop also showed pressure sensing foot pads and hand tracking system both using their fabric sensor technology. The company has been shipping its sensors into musical instruments sold by its sister company KMI, one such example was the BopPad a musical drum pad that is in the market already. BeBop is silicon valley based startup, expecting to go into mass production this year.

Open Source Foundries IoT Zephyr, Linux, IoT Gateways, Bluetooth Mesh microPlatforms demo

Posted by Charbax – October 10, 2017

Open Source Foundries is a spin off company off of Linaro, composed of a talented group of engineers to work more directly with companies, OEMs, ODMs, small, medium to large companies to bring new open source products and solutions more rapidly to the market. Leveraging all the work done by Linaro and speeding up the time to market, enable rapid product development, here demonstrating some of the open source IoT solutions provided based on Zephyr on ARM Cortex-M and Linux on ARM Cortex-A using the Linaro Technologies Division (LTD) microPlatforms system.

The lack of a secure IoT solution has the industry scrambling. The Open Source Foundries team believes that a world can exist in which all connected devices can be secured and updated in a timely fashion. In this demonstration shown at the Linaro Connect San Francisco 2017, the team showcases its secure end to end FOTA (firmware over the air) solution implementing the latest in connected technologies.

At Open Source Foundries, software is their passion, hacking hardware is their favorite past time, so they have created the OSLight project to convert off the shelf hardware into secure connected devices. They have inserted a Red Bear NRF52 BLE Nano 2 into these lamps, to allow them to communicate over BLE with various cloud services. In the first demo, they demonstrate creating a secure BLE mesh network with these lamps. They show the ability to securely pass messages through the mesh network to control the state of the LED lamp. The next demo shows a set of 96Boards Nitrogens sending temperature data to the SoftBank IoT Cloud with the ONEM2M protocol using 6lowpan over BLE. The third and final demo introduces a variant of the OSLight project, a fully 3D printed light bulb. Instead of a simple LED array it has a 12 LED WRGB NeoPixel which is powered by line voltage, stepped down to 5VDC.

For microcontrollers, they offer their Zephyr microplatform, an open source software reference based on Zephyr RTOS and MCUboot. This software stack implements secure boot, unified microkernel, and IP (TCP or UDP) using 6lowpan over BLE. At the protocol level they've embraced industry standards such as LWM2M/ONEM2M/HTTPS/MQTT to provide an array of options for their customers, whilst ensuring no vendor lock in. Open Source Foundries subscribers are offered continuous validated software updates throughout the life of their product for a fixed monthly subscription fee.

On the gateway, they offer their Linux microplatform, which is again, an open source reference based on the latest Linux kernel version, and a minimal Yocto based userspace with a container runtime (Docker). By isolated the OS from the containers, each can be updated independently while providing limitless potential for the applications it can run. For updates they again implement standards, and stay vendor neutral to allow their customers to choose the solution that is right for them. Continuous validated updates for the OS and containers are also offered for this platform for a reasonable fixed monthly fee.

Peratech 3D force-sensing Touch sensors

Posted by juliusaugustus – July 15, 2017

Peratech 3D multi-touch matrix sensors unlock the next-generation in HMI experiences, enabling new gestures, simplified interfaces, and endless flexibility. So sensitive they can be integrated under multiple top surfaces including plastics, metals, glass and flexible displays. Better still, they can be deployed in curved applications. Because our matrix sensor can be dynamically reconfigured through firmware, a single or small number of sensor design(s) can fit multiple applications, dramatically reducing development and tooling costs. Peratech 3D multi-touch sensors are low power, immune to EMI and water events, work with gloved hands and passive stylus, and can be transparent as well as opaque. Filmed at the SID Display Week.
