Gustatory technology stimulates on-line get-togethers

It has been known for some time that over or under responsivity to sensory stimulation encountered in everyday life, such as noise, light and smell, can be a cause of anxiety and stress [e.g. Lipowski, 1975].  Most virtual reality systems provide visual and audio stimuli through headsets and tactile stimuli can be provided through haptic devices; however, that leaves two senses under stimulated: smell and taste.  So, researchers have been exploring how to extend virtual reality to include smell and taste in order to give a complete sensory experience and thus reduce the level of stress and anxiety that many people feel when using immersive reality systems.  This had led to digital scent technology that allows smells to be transmitted electronically [e.g. Isokoski et al, 2020].  So, it’s time to update your preferred communication tool to one that allows you to smell that fresh cup of coffee your colleague has just brewed before joining the meeting from their home-office.  Of course, if they have not taken a shower recently then you might want to ‘mute’ the smell function!  These advances in technology have led a spin-out company, Day91, to start work on gustatory technology that modifies the water in your glass to simulate the after-work drink that your team-mate is enjoying during your virtual get-together online.

Devaluing novelty: not all that glitters is gold

My regular readers will have recognised the novel nature of a blog that seeks, in a unique way, to present promising engineering ideas in a favourable and robust manner.  Actually, I hope my regular readers will recognise this opening sentence as completely uncharacteristic.  It was a blatant effort on my part to include the five words, underlined, with positive meanings that are most used in the titles and abstracts of articles published in clinical research and the life sciences.  A recent survey of more than 100,000 articles showed the prevalence of these words, with them being used significantly more in articles in which the first or last authors were male compared to those in which the first and last authors were female.  In other words, female authors are significantly less likely to describe their research findings in these positive terms and this influences the subsequent citations of their work and probably their prospects for research funding and advancement.  Sunday was International Women’s Day and, hence this is an appropriate week for everyone responsible for decisions about research to be conscious of this trend.  They should also be aware that the use of these positive words has increased in clinical and life sciences research by around 150% in the fifteen years to 2017.  In other words, the modesty of researchers has declined and they are more likely to describe their results as ‘novel’; however, I think it is unlikely that the results are any more novel than typical results published 20 years.  Of course, like most researchers, I always think my last breakthrough is the most exciting yet but many of us have been letting that enthusiasm lead us to exaggerate its novelty and value.

Try the impossible to achieve the unusual

Everyone who attends a certain type of English school is given a nickname.  Mine was Floyd Patterson. In 1956, Floyd Patterson was the youngest boxer to become the world heavyweight champion.  I was certainly not a heavyweight but perhaps I was pugnacious in defending myself against larger and older boys.  Floyd Patterson had a maxim that drove his career: ‘you try the impossible to achieve the unusual’.  I have used this approach in various leadership roles and in guiding my research students for many years by encouraging them to throw away caution in planning their PhD programmes.   I only made the connection with Floyd Patterson recently when reading Edward O. Wilson‘s book, ‘Letters to a Young Scientist‘.  Previously, I had associated it with Edmund Hillary’s biography that is titled ‘Nothing Venture, Nothing Win’, which is peculiar corruption of a quote, often attributed to Benjamin Franklin but that probably originated much earlier, ‘Nothing ventured, nothing gained’.  I read Hillary’s book as a young student and was influenced by his statement that ‘even the mediocre can have adventures and even the fearful can achieve’.

When seeing nothing is a success

In November I went to Zurich twice: once for the workshop that I wrote about last week [see ‘Fake facts and untrustworthy predictions’ on December 4th, 2019]; and, a second time for a progress meeting of the DIMES project [see ‘Finding DIMES’ on February 6th, 2019].  The progress meeting went well.  The project is on schedule and within budget. So, everyone is happy and you are wondering why I am writing about it.  It was what our team was doing around the progress meeting that was exciting.  A few months ago, Airbus delivered a section of an A320 wing to the labs of EMPA who are our project partner in Switzerland, and the team at EMPA has been rigging the wing section for a simple bending test so that we can use it to test the integrated measurement system which we are developing in the DIMES project [see ‘Joining the dots’ on July 10th, 2019].  Before and after the meeting, partners from EMPA, Dantec Dynamics GmbH, Strain Solutions Ltd and my group at the University of Liverpool were installing our prototype systems to monitor the condition of the wing when we apply bending loads to it.  There is some pre-existing damage in the wing that we hope will propagate during the test allowing us to track it with our prototype systems using visible and infra-red spectrum cameras as well as electrical and optical sensors.  The data that we collect during the test will allow us to develop our data processing algorithms and, if necessary, refine the system design.  The final stage of the DIMES project will involve installing a series of our systems in a complete wing undergoing a structural test in the new Airbus Wing Integration Centre (AWIC) in Filton, near Bristol in the UK.  The schedule is ambitious because we will need to install the sensors for our systems in the wing in the first quarter of next year, probably before we have finished all of the tests in EMPA.  However, the test in Bristol probably will not start until the middle of 2020, by which time we will have refined our algorithm for data processing and be ready for the deluge of data that we are likely to receive from the test at Airbus.  The difference between the two wing tests besides the level of maturity of our measurement system, is that no damage should be detected in the wing at Airbus whereas there will be detectable damage in the wing section in EMPA.  So, a positive result will be a success at EMPA but a negative result, i.e. no damage detected, will be a success at Airbus.
