How can we elevate life quality for patients in some of the world's most underserved regions?

Negative Pressure Wound Therapy (NPWT) is a proven and efficient method for treating chronic wounds. This is particularly useful in low- and middle-income countries, where diseases like leprosy, limited healthcare, low infrastructure and poverty combine to make chronic wounds and commonality. 

Devices for treatment are costly, overly complicated and not built to serve the regions that need them the most. 

Amid frequent power cuts, Dr Suraj Mahajan and Lead Biomedical Engineer Arjan Knulst of the Green Pastures Hospital and Rehabilitation Center (part of International Nepal Fellowship), join HardwareX via connection from Nepal to share the motivation, process and intended impact of WOCA - a fully open-source NPWT device designed in close collaboration with the Delft University of Technology, and with Nepal's citizens in mind.

Open Hardware Talks is back. This series invites interdisciplinary experts and advocates to a roundtable discussion on the most relevant topics in open-source hardware.

Discoverability: How To NOT Reinvent the Wheel.

Open and collaborative development promises to accelerate innovation by allowing individuals and teams to share new ideas, build on top of existing ones and improve designs according to multiple use cases. So, how do you find out what is already out there? And what can make your design easier to discover for the right collaborators?

In this roundtable talk, Victoria Jacua (Open Source Medical Supplies, Global Distributed Tracking), Robin Vobruba (Open Know-How, Open Source Ecology Germany), and Nathan Parker (Open Know-How, Internet of Production Alliance) sit down to discuss the challenges, potential and possible consequences of making an open-source hardware design more discoverable.

Much like plants can turn carbon into energy, researchers have been striving to scale the potential of photocatalytic CO2 reduction. Promising as the technology may be, little progress has been made to scale its potential. If the net human-caused CO2 reduction target of 45 % from 2010 levels is to be reached by 2030, the science must be shared.

That is the notion that propelled Prof. Dr. Jennifer Strunk and Dr. Nikolaos Moustakas PhD, former research colleagues at the Leibniz Institute for Catalysis (LIKAT), to open-source their High-Purity Gas-solid Photoreactor design. In this episode, we journey to Rostock in the north of Germany to see the reactor in action and to unfold the possibilities and limitations of reducing carbon using the power of nature.

Did you know that honey bees dance?

When honey bees return to the colony from foraging, they share info about their journey with their fellow honey bees by dancing. Besides getting the boogie on, however, little is known about how far honey bees go foraging and what ecological factors impact their journey, e.g. pesticide exposure.

In this episode of HardwareX, Entomologist Margarita López-Uribe, Ph.D., specialised in bee species, together with Doctoral Student of Electrical Engineering, Diego Penaloza Aponte, of Penn State College of Agricultural Sciences, explain how open-source technologies and collaboration across scientific fields helped pave the way for an automated low-cost monitoring system - and what it takes to tag 6000 bees without getting stung.

To explore the specifics, check out the hardware on HardwareX.

The advancement of low-cost sensors has sparked a boom in air quality monitoring devices. From backpack add-ons to citizen bicycles, air quality devices are enabling citizens to get involved in monitoring local air quality.

When looking at global air quality maps, however, the data for South America and Africa remain scarce. As primarily consumer-based products, these devices remain subject to demand and supply, limiting access to local air quality and air pollution for those who need them the most. Though the number of open-source designs is growing, incomplete and non-standardised documentation renders many viable designs unusable.

In this episode, Colombia-based Engineering Physicist, MSc., Daniel Mauricio Pineda, takes us through the design of a fully documented, open-source air quality monitoring device that allows for remote data gathering and customisation.

What if research labs didn't have to reinvent the wheel all the time?

Rodents like mice and rats play a pivotal role in neuroscientific research. Through a process known as 'head fixation', scientists surgically implant cannulas and electrodes to measure neurophysiological activity. As mice share roughly 95% of our DNA, head fixation experiments greatly contribute to advancing our understanding of the human brain and diseases like Alzheimer's and Parkinson's.

While head-fixation is common in many labs, proprietary systems are often expensive and inconsistent. This leads many labs to create ad hoc DIY systems at the risk of causing harm to the research animals and impeding the results.

In this episode, we sit down with Zack (Isaac) Weaver, PhD, to explore the ethical and design-specific considerations behind his open-source head gear fixation system. With animal well-being in mind, we explore the multi-stakeholder benefits of open-source hardware in research.

Open-source hardware is a collaborative effort. A special thanks to co-authors Michael R. Tadross and S. Aryana Yousefzadeh and all the labs and members who contributed to the design by trying and testing various iterations.

Did you know that our understanding of basic functions such as memory, learning and sleep is largely thanks to a giant sea slug?

For more than 50 years, Aplysia Californica, a type of slug also known as the California Sea Hare, has been important for understanding how the nervous system works and for investigating the cellular and molecular basis of behaviour. As an essential resource for neurological disease research across the globe, there are large incentives to preserve the species, including sampling and storing its genetic material.

This is easier said than done, as the Sea Hare's genetic material is both delicate and complicated to handle. Cryopreservation methods are simultaneously advancing too slowly, leaving researchers worrying that the field of neurophysiology is running out of time.

Together with Marine Biologist Jack Koch, we take a look at a standardised open-hardware solution that allows for easy sampling and packaging of genetic material for cryopreservation research. Diving into the world of Aplysia Californica, we explore open-source hardware as a revenue stream, and how going open can benefit more than one species.

The design published in HardwareX was made possible through work partly funded by the United States National Institutes of Health (NIH) Office of Research Infrastructure Programs (ORIP) and completed in partnership with the NIH National Aplysia Resource.

Urgent needs require urgent solutions, but is open-source always the answer?

The UN aims to eradicate malaria in all countries by 2030. However, in some parts of the world, incidents are increasing as the parasites transmitting the disease grow increasingly tolerant to treatment drugs.

A novel treatment method using microwaves to kill the parasite shows promising results. One that could save both lives and economies in Africa, where a majority of malaria incidents and deaths are registered each year. With the release of an open-source portable device for studying the malaria parasite’s growth inhibition via microwave exposure, researchers hope to accelerate the development of a deployable treatment device sooner rather than later.

In this episode of HardwareX, Biochemist and researcher Dr Carmenza Spadafora joins us from her home in Panama as she explains how quantum physics and technological innovation have paved the way for a potentially groundbreaking new method for malaria treatment. A patented method, Dr Spadafora shares her thoughts on why open-source might not always be the best choice.

How inclusive are advanced prosthetics technologies?

The global demand for prosthetics and orthotics is only expected to rise. Yet, access to affordable and innovative solutions varies greatly at local, national and international levels. And while 3D printing has greatly contributed to making prosthetics available in low-income and developing regions, the benefits that robotics and technological innovation bring users remain highly exclusive.   

This may be about to change. In an attempt to make high-tech prosthetics solutions more accessible, Professor in Biomechatronics at the University of Agder in Norway, Filippo Sanfilippo, along with his colleagues (Martin Økter, Jørgen Dale, Hua Minh Tuan, Muhammad Hamza Zafar, Morten Ottestad) have published an open-source, low-cost sensorised elastic actuator design that promises to shift innovation from the market to the commons.

What does it take to make research catch up with climate change?

The Arctic regions hold crucial information about the environmental impact of rising temperatures. Calving glaciers and treacherous territories make it a life-threatening mission to collect it though.

As autonomous technologies improve, drones, boats and rovers are increasingly being deployed in place of humans to sample, monitor and manage marine and aquatic systems. However, as costs can range in the millions, the value these technologies can provide researchers is relevant to their cost. That is why Daniel F. Carlson and Claus Melvad put it to a group of engineering students at Aarhus University in Denmark to design a low-cost, lightweight and replicable drone for accompanying them on missions to Greenland. In this episode, we take a look at the Naval Operating Research Drone Assessing Climate Change (NORDACC) and discuss how open-source principles coupled with citizen science could accelerate climate change research - and results.

Why did high-tech farming go bust?

Vertical Farming was one of the big new technologies of the early 2010s. By growing crops vertically with less water and no pesticides, big vertical farms promised to revolutionise food production. So why are the same vertical farms going bust across Europe and the US just ten years after they boomed?

In this episode, we journey to Cambridge University in England to meet Vijja "Pat" Wichitwechkarn. An AI researcher working on agricultural robotics, he has developed a fully automated and scalable indoor farming system - MACARONS - published on HardwareX. In this episode, we address why vertical farming keeps missing the goal, and how open-source technologies could propel it to become the food tech solution we all hoped for.

How can we make life-saving medical equipment more accessible in areas under blockade, with low infrastructure, or with limited resources?

In a time where almost every region in the world is seeing a rise in conflict, tourniquets have become increasingly necessary for avoiding excessive civilian casualties. Yet, proprietary tourniquets remain largely geared toward male military personnel, not women and children. Even if this changes, proprietary tourniquets remain expensive and largely inaccessible in regions where they are needed most.

In this episode, Dr Tarek Loubani of Glia and Victoria Jaqua of Open Source Medical Supplies (OSMS) take us from Gaza to Ukraine as we explore the development, testing and scaling of the open-source tourniquet and the open-source tourniquet tester published on HardwareX.
