Electronically displayed information is everywhere; smartphones, laptops, TV, advertising billboards, wearables… the list of devices we use goes on and on. These displays are mostly based on either liquid crystal (LCD) or organic light emitting diode (OLED) technology. These are great technologies, but they are not without limitations. We have all experienced the poor readability of a phone screen in sunlight and short battery life, largely due to the high power consumption of the display. Recent research has also shown that evening use of these light-emitting devices can negatively affect sleep and next-morning alertness.
So how can we design the next generation of displays to address these issues? A promising approach is to develop displays which can reflect natural ambient light or room lights to illuminate the screen, rather than using the powerful backlighting used in LCDs. Deployed in eReader devices, reflective displays provide vastly improved power consumption and outdoor readability. But this current form of reflective display technology cannot render good colour, nor deliver video rate refresh rates – a major limiting factor to wider application.
Immersive technologies such as virtual and augmented reality are currently taking the world by storm. Over the past three years, we’ve seen a huge interest in immersive technologies from the likes of advertising agencies, games developers, construction companies and more…
Immersive technology is not a new concept. Experimentation with virtual and augmented reality has been taking place since the 1960s, hidden inside research facilities across the world. The Sword of Damocles is considered by most to be one of the first virtual reality headsets. Built by Ivan Southerland and Bob Sproull in a laboratory at MIT, it was a large and somewhat dystopian looking device. The device was so heavy that it had to mounted to a mechanical arm attached to the ceiling when in use.
Modern engineering has moved on from the stage where hardware was always used for manufacturing, and computer software was necessary for programming. Today, we are close to being able to use purely biological approaches to produce drugs, food, clothing and even industrial goods. This discipline is called biological engineering, and progress has accelerated in the last ten years thanks to massive drops in the price of both DNA production and characterisation. However, the complexity of biology and the long time it takes to prototype proteins is still a major roadblock to progress.
At the end of last year, creative images and video spanning tissue engineering, aircraft engines and nanotechnology won prizes in the University of Cambridge Department of Engineering 2017 ZEISS Photography Competition. Here are some of the incredible visuals that took the top prizes.
Why on earth would anyone use 2 weeks of annual leave to build a model railway? As STEM Ambassadors, we often joke that championing Science, Technology, Engineering and Maths is a full-time job. Problem is, we already have day jobs, as engineers. That’s why we spent our summer holiday being filmed by Love Productions for a Channel 4 show, surviving clouds of midges and rain.
You are probably questioning our sanity now, but when you’re as acutely aware of the need for more engineers in your industry then it’s hard not to seize every opportunity to promote the industry in a more positive light. Oh, and it sounded like a great challenge to take on an engineering project of such a grand scale, in a really tight time limit. Still not convinced you that it was a good idea? Well, we’ve interviewed each other to see if we can explain a bit more behind our reasons.
An engineer, scientist and social tech entrepreneur, I am currently studying for a PhD in Electrical Engineering at the University of Cambridge. The co-founder of two social tech start-ups, ‘Wudi‘ & ‘Favalley‘, my vision is to innovate, transform and empower society, revolutionising education through technology. I aspire to provide a platform for young people to become positive change makers for society.
Being in love with physics, exploring, and creating ‘stuff’, engineering came as an obvious choice to me. Trying to understand the mysterious ‘electric shock’ I received from objects as a child motivated me to take up electrical engineering as my specialisation. I started off with an undergraduate degree, then moved on to do a master’s and am now pursuing a PhD in the same area.
Over the years, drones have gained popularity in the engineering and construction industry. Small and simple to fly, drones can quickly snap photos from every angle, giving a bird’s eye view of inaccessible areas. But thousands of photos are meaningless without the right tools to manage them. Drone mapping technology, or ‘photogrammetry’, helps make this task easier by converting drone photos into a 3D model. However, having only the 3D model is still not practical in most engineering work, especially in infrastructure inspection and maintenance. Trik is a specialised system, creating a 3D database. This allows engineering companies to make the most of their drone data.
Photography was invented here in the UK, back in 1830s. There are so many layers to a photograph: the ability to share a story and to evoke emotions; the power to expand the viewer’s field of vision; the universal language it speaks; and most importantly, the ability to create new meanings. 180 years on, photography continues to fascinate us, yet it remains inaccessible to many parts of the developing world. This is particularly true for marginalized women and girls, where socio-economic and cultural barriers prohibit them from using digital tools. 200 million fewer women than men own mobile phones.
