When Electronics Carry Responsibility: Building Sustainable Healthcare Tech from Day One

Designing devices that protect both patients and the planet

Healthcare is becoming increasingly electronic. From wearable sensors and smart patches to remote diagnostics and continuous monitoring, digital technologies now sit directly on the human body — sometimes even inside it. These innovations promise earlier detection, better outcomes and more personalised care. Yet beneath this progress lies a growing contradiction.

Many of the technologies designed to protect human health are themselves environmentally unsustainable. Short-lived medical electronics, complex material combinations and disposable devices contribute silently to a global waste stream that is expanding faster than regulation, recycling capacity or ethical reflection.

The problem is not simply one of waste management. It is structural. Electronics are still largely designed according to a performance-first logic: smaller, faster, cheaper. Sustainability is often introduced later — as a compliance step, a reporting requirement or a post-production fix. In healthcare, where reliability and safety are paramount, this linear design mindset has proven particularly difficult to challenge.

It is precisely this systemic tension that Professor Shweta Saxena Agarwala has been working to address. Her research sits at the intersection of printed electronics, sustainable materials and healthcare technologies — a space where engineering decisions quickly become ethical ones. Rather than treating sustainability as an external constraint, Saxena Agarwala approaches it as a foundational design principle. Not something to be added, but something to be built in.

Designing before the problem exists

“Sustainability is not a layer you apply at the end. Once materials are permanently bonded, separation becomes almost impossible. If you don’t think about circularity at the design stage, you’ve already lost the opportunity.”
— Professor Shweta Saxena Agarwala

In conventional electronics, materials are optimised for performance. Conductivity, durability and cost dominate early design decisions. But when these materials are combined using toxic adhesives or irreversible bonding processes, recycling becomes more theoretical than practical. In healthcare technologies — particularly wearables and skin-mounted sensors — this challenge intensifies. Devices are often used briefly but require high precision. They may touch vulnerable patients, operate in sterile environments and generate sensitive data. As a result, disposability has long been accepted as unavoidable.

Saxena Agarwala’s work challenges that assumption. By focusing on biodegradable substrates, biocompatible conductors and design-for-disassembly principles, her research asks a different question: what if temporary medical technologies were designed to disappear — safely and intentionally — after use? This shift reframes sustainability not as a trade-off against performance, but as a different form of performance altogether. One measured not only by accuracy or longevity, but by what happens when the device’s task is complete.

Innovation between disciplines
Such questions cannot be answered within a single field. Sustainable healthcare electronics sit at the convergence of materials science, electrical engineering, medicine, environmental science and economics. Yet academic and institutional structures are often still organised along rigid disciplinary lines.

At Ahmedabad University, where Saxena Agarwala also serves in an academic leadership role, interdisciplinary collaboration is not treated as an exception but as an organising principle.

“Innovation doesn’t happen inside disciplines anymore. It happens in the space between them — where engineers, clinicians and social scientists start asking different questions together.”
— Professor Shweta Saxena Agarwala

In practice, this means students and researchers are encouraged to engage beyond their technical comfort zones. Engineering students work alongside ecologists. Healthcare applications are examined not only for functionality, but also for cultural acceptance, logistics and lifecycle impact.

This educational philosophy reflects a broader shift in how technological responsibility is understood. Complex problems — from electronic waste to healthcare access — cannot be solved through technical optimisation alone. They require systems thinking: an ability to see how materials, users, infrastructure and incentives interact over time.

For Shweta, this also demands a different understanding of leadership. Academic direction is not only about defining research excellence, but about creating institutional space for uncertainty, experimentation and early failure — especially in areas like green chemistry and sustainable materials, where progress is rarely linear.

Circularity in healthcare: from disposable to deliberate
Nowhere are these tensions more visible than in healthcare itself. Hospitals depend on strict hygiene protocols, reliability standards and predictable performance. These requirements have historically favoured single-use devices. Yet the environmental cost of this model is becoming impossible to ignore.

Shweta sees opportunity precisely in rethinking what “single-use” means.

“We need to move from disposable to biodegradable — from products that are thrown away to systems that are designed to safely return to nature or to controlled recovery loops.”
— Professor Shweta Saxena Agarwala

Emerging approaches include transient electronics that dissolve after use, compostable sensor platforms and modular medical devices designed for refurbishment under manufacturer responsibility models. In parallel, service-based models are gaining relevance. Instead of selling devices outright, manufacturers retain ownership of materials and remain responsible for maintenance, recovery and reuse. This shift aligns economic incentives with material stewardship — a core principle of the circular economy.

Such models are still early, particularly in regulated healthcare environments. But they represent a fundamental change in mindset: sustainability becomes not a constraint on innovation, but a framework that reshapes it.

AI as accelerator — not decision-maker
Material innovation has traditionally been slow. Discovering combinations that are simultaneously conductive, flexible, biocompatible and biodegradable can take years of trial and error. Here, data-driven approaches are beginning to change the pace.

“With AI and machine learning, we can virtually test thousands or even millions of material combinations before we ever step into the lab. It allows us to search much faster for sustainable options that would otherwise remain hidden.”
— Professor Shweta Saxena Agarwala

Rather than replacing scientific judgment, AI functions as a compass — narrowing vast design spaces and accelerating discovery. It enables researchers to explore sustainability not as a limitation, but as a rich design domain. Yet Shweta remains cautious about technological solutionism. Speed alone does not guarantee responsibility. AI can accelerate choices, but it cannot define values. Those must still come from human intention and institutional priorities. In this sense, artificial intelligence becomes part of a broader toolkit — powerful, but directionless without ethical orientation.

A global challenge, unevenly distributed
The sustainability question cannot be separated from geography. Europe has taken a leading role in regulatory frameworks, pushing industries toward lifecycle accountability through policies such as the Green Deal. In contrast, countries like India face a different reality: vast populations, constrained resources and urgent healthcare needs.

This has given rise to frugal innovation — the ability to deliver meaningful impact with minimal material and financial input. This ingenuity is not merely a workaround for resource-constrained environments; it offers a vital lesson for the West in shedding the habit of over-engineering and returning to the essence of what makes technology truly effective and sustainable.

For Swheta, the future lies not in choosing between these models, but in connecting them.

“We must combine Europe’s regulatory strength with the scalability and ingenuity of the Global South — otherwise we risk exporting our environmental burden instead of solving it.”
— Professor Shweta Saxena Agarwala

Without cross-border cooperation, sustainability risks becoming unevenly distributed: high standards in one region and mounting electronic waste in another. Responsible electronics, therefore, cannot be a regional ambition. It must be a global design language.

Redefining the engineer’s question
At its core, Shweta’s work points toward a deeper cultural shift in engineering itself. For decades, success has been measured by whether a technology functions as intended. Increasingly, a second question demands equal attention: what happens after it stops functioning?

This reframing transforms the role of the engineer. Technical skill remains essential — but insufficient. The next generation must also understand systems, supply chains, users and unintended consequences. Not every engineer needs to become an expert in sustainability. But every engineer must recognise that design choices ripple outward — across environments, economies and societies.

In that sense, sustainable healthcare electronics are not just a technical frontier. They are a test case for how innovation will be defined in the decades ahead. As technologies move closer to the human body, responsibility can no longer remain distant from design. And when electronics become intimate, sustainability can no longer be optional. It becomes part of the technology itself.
