Idea Fund Award – a virtual white stick to help blind people ‘feel’ their surroundings, objects and textures.

Our latest ‘I’ve got an idea’ Fund award is to Matt Carlon, an Industrial Design Engineer with over 20 years experience in disability product development.

In Matt’s words, “my idea is for a ‘virtual’ white stick that uses LIDAR technology to allow blind people to ‘feel’ their surroundings, objects and textures. The design has a point displacement pressure pad that presses against the users finger, much like a braille dot, a variable amount directly correlating to a LIDAR measurement. The LIDAR scale and sensitivity can be adjusted by the user with a thumb wheel and rocker. The thumb wheel on the top adjusts the far distance limit so the user can ‘click’ half a metre increments indicating a ‘measurable’ distance; the rocker (which has the pressure pad within it) pivots to increase the near distance limit and the sensitivity of the displacement feedback allowing the user to touch and feel the shape of the object they are pointing at. My hope is that it will give a improved scope for orientation, in the case of walking the user could scan further ahead than a step, to the side they could orientate with buildings; the tactile response will provide a new intuitive sensory experience to understand their environment, they could ‘see’ sculptures and feel what a park ‘looks’ like.

Idea Fund Award – using urban river waste to create aesthetic, floating structures for growing food

Our latest ‘I’ve got an idea’ Fund award is to Johana Hartwig, a Cardiff based artist exploring creative solutions to urban environmental issues. Her work has focused on water bodies within populated spaces and public access to natural resources. 

Johana is inspired by the structures of the floating gardens of south Bangladesh that rise and fall with the flood water. Utilising the point at which the 2 rivers Ely and Taff feed into Cardiff Bay, Johana’s idea is to try to create a mass hydroponic system of some kind, grown on the waste we discard. The work responds to human impact in natural environments and will use the Cardiff Bay Marina as a testbed for the creation of organic, buoyant structures that could be used for current and future urban farming. If successful, the food grown can be given to the local food-bank and cafe and Cardiff Met University have agreed to test the produce to check if it would be suitable for human consumption.

Johana has gained permission from Cardiff Bay Harbour Authority to collect buoyant plastic waste and permission from the Marina to fabricate structures using this waste to trial floating large growing platforms on.

Johana’s is a fascinating and challenging project which may or may not work technically but will certainly visibly stimulate thinking and conversation about rivers and waste and new ways of growing food in the centre of a city.

Idea Fund Award – wearable electronic health record for resource-constrained settings

Our latest award is to Brandon Smith to help him further research, prototype and experiment with his idea of ‘Amulet’ – an ultra-low-cost wearable electronic health record (EHR) designed for rapid deployment in resource-constrained or disrupted healthcare settings, such as in conflict zones, humanitarian crises, and with displaced populations. Brandon is a post doc researcher with a background in both medicine and electronic engineering and experience of collaboration with overseas partners.

His idea is that Amulet will be able to securely store critical health data: diagnoses, management plans, allergies, medications, and next-of-kin details. Healthcare personnel will be able read and write to the device using already owned, ubiquitous technologies such as mobile phones. The goal is for Amulet to eliminate the need for substantive network infrastructure (e.g., cloud servers, computer access, substantive internet connectivity), bridging chasms in record keeping, information, and knowledge, empowering providers and patients with a resilient, accessible tool for delivering quality care worldwide.

We wish Brandon well with this challenging but potentially transformative project.

Idea Fund Award : Detox Bio Embellishment: Non-mined gemstones

Our first ‘I’ve got an Idea’ Fund award of 2025 is to Cassie Quinn for her lab experiments into creating reflective sparkles using biopolymers. Intriguingly, the idea was born from a mistake made in an experiment of Cassie’s while producing wastewater-cleaning sequins. Her project will now investigate this phenomenon (see image) and how to reproduce it. Her goal is to retain biodegradability in sequin and embellishments and creating gemstones like amber and opal using non-extractive methods.

Why does this matter? For a start, it’s reported that British women purchase 33 million sequinned garments every festive season, with 1.7 million ending up in landfill after only 5 years and 35% of microplastics being released into the world’s oceans. These conventional sequins are made of polyester film or vinyl, which involve toxic and carcinogenic chemicals that cause significant environmental and health risks.

You could argue, why don’t we ‘simply’ ban sequins if they generate such toxic waste. But our use of and attraction to glittering objects like sequins is certainly no trivial modern whim. Their construction and decorative use reach back in time for at least 12,000 years and across many diverse civilisations. It is only in recent times that we have switched from first shells and later metal coins to toxic micro plastics for sequin construction. And why is sparkle important to us? Certainly, our fellow, non-human creatures have evolved bright, eye catching colours and display to attract others – while we have done the same through articles we wear or carry or by directly painting our faces and bodies. Some research in evolutionary aesthetics also suggests that humans prefer shiny objects because glossiness connotes water which has always been vital for life.

So, we wish Cassie luck in exploring ways to give us sparkling sequins without microplastics, dyes and their toxic waste effects.

Latest Idea Fund Award

We are are pleased to announce the ‘BLCK BOX’ project as the latest winner of an ‘I’ve got an idea’ Fund award .

BLCK BOX is the idea for an innovative tool that uses granular data from sensors to create digital twins for commercial buildings. The digital twin is capable of accurately quantifying heat loss on a room-by-room basis that is viable for a reliable decarbonisation strategy for commercial buildings. The model can be used to highlight fabric improvement opportunities as well as provide accurate measurements for heat pump sizing

Raw data of mix of return and flow temperatures (pipe temperatures) and ambient temperatures

The Prospectory Idea Fund is covering the purchase of the necessary sensors for the project’s initial experimentation in 2 test buildings to validate the concept.  The plan is to use the first part of the 2024/25 heating season for data collection and digital twin building and the 2nd half of the heating season to validate the outcome of the new models. One data point per sensor will be collected every minute for a period of 6 weeks generating approximately 1 million data points to build a sophisticated digital twin. The project team will then validate their calculations with smart gas meters and also heat meters already installed in the buildings.

The Idea Fund always welcomes applicants who are testing their ideas through their own DIY experimentation however sophisticated or simple in kind.

Keeping the elderly warm this winter……

Over the past 3 years, I have been researching the problem of how to keep people warm in our wide diversity of UK housing without wasting energy and keeping costs manageable. My studies have included conventional central heating, heat pumps and Infrared heating and, most recently, I sampled how warm 77 individuals in 61 different homes felt at particular moments in time over 30 winter days. The current air temperature in the room they were in was also recorded along with their recent activities.

The most striking findings from the studies are:

  • there is wide variability in how warm individuals feel on a 7 point scale… even compared to other members of their household
  • the current air temperature is not a significant factor (only accounting for 14% of this variance)
  • people’s felt warmth varies at different times due to a complex and unpredictable combination of ‘in the moment’ physiological, physical, psychological, behavioural and contextual factors
  • the different forms of heat: convection, conduction or radiation matters. Interestingly, 87% of the 71 houses studied had some form of hybrid heating that they used in addition to their main form of heating, e.g. log burners, agas, fan heaters or portable radiators.

Co-incidentally, our community hydro company, Talybont on Usk Energy, has funded an offer of 25 electrically heated throws to elderly members of our small rural community this winter if they are suffering from feeling cold. I have spent the past week delivering throws to folk who have requested them. Anecdotally, in line with my research studies, it’s proving a further example of the fact that warm air doesn’t actually heat us (until it reaches 37 degs!) but is important in reducing how quickly we lose bodily heat. In every home I’ve visited, the air has felt comfortably warm (20 degs plus) thanks to the central heating or heat pump being on but residents still feel uncomfortably chilly in their legs or back or shoulders and are often operating a portable electric bar or fan heater to supplement their central heating.

If people are sitting still for large stretches of time and are also elderly and frail, they can become cold and then need either vigorous exercise or a conductive or radiant heat source to warm their bodies directly. The good news is that electrically heated throws deliver a conductive effect quickly and effectively and do so by consuming only 160w – about 6 times less energy than an electric heater which is attempting to raise the air temperature. The heat level is also under each person’s direct control and studies have shown that people simply feel warmer if they know they are in control of the heat source – hence the temptation to turn up the thermostat even if that isn’t actually necessary or effective in raising their body heat.

Food for thought…

‘I’ve got an idea’ Fund – braille project news

Great to hear update news from one of our 2023 fund winners on their experimental development of a digital Braille Reader to include graphics to enable blind people to play digital games.

Ed has sent us 2 short videos of recent developments . The first video shows a user playing the game experiencing the value of a multi-line display reader so users can effectively scan the display to pick up action and respond. The 2nd video shows a blind 16 year old programming his own new game using the multi-line braille display.

Idea Fund Award – Thermal insulation from crop waste

We are delighted to announce our latest ‘Ive got an idea’ Fund award to Antoinette Oni – an architectural designer, materials researcher and artist.

Antoinette is working on how to create thermal insulation boards from a composite based on abundant crop waste material here in the UK. She explains: “Finding uses for agricultural waste byproducts has become increasingly popular for material researchers in recent years as it’s such abundant biomass. However, a lot of the research is coming from tropical regions using crop waste relevant to those climates. What I’m proposing is utilising the most abundant crop waste in the UK, straw, to make a board that is completely circular and non-toxic with no additional binders. The process I’m developing draws on the amazing natural capabilities of the straw fibres. I’ve carried out extensive research and I’m yet to see my unique process published in any academic paper so far. Also, the application of this board as thermal insulation in the British climate is underexplored.” 

Our funding will enable Antionette to purchase the materials and equipment she needs to experiment with processing the material, build her first prototype and install it in conditions to test its durability and performance. We will follow her project with interest.
