Electrical engineering is poised for major innovations and disruptions in 2024. With cutting-edge research across areas like semiconductors, renewable energy, robotics, and biomedical devices, several pivotal trends are expected to shape the industry. Here are eight major movements that will redefine electrical engineering.
- Skyrocketing Investments in Next-gen Semiconductors
Legacy semiconductors face limitations in catering to modern computing needs regarding speed, efficiency, and capabilities. This has fueled massive investments in developing next-generation semiconductors using novel nanomaterials like graphene and molybdenum disulfide. Alongside Materials research focused on 2D heterostructures and topological insulators will enable disruptive applications.
Global giants like IBM, Apple, and Intel have infused billions in strategic partnerships with research consortiums and chipmakers. Expert projections indicate semiconductor R&D spending to exceed $100 billion in 2024. Rapid prototyping using 3D printing also holds huge promise. All these factors signal a seismic shift as next-gen semiconductors get ready for prime time.
- Surge in Adoption of Autonomous ‘Intelligent’ Robots
Robots with continually advancing AI-powered ‘brains’ saw ballooned interest post-2020. Electrical engineers are now funneling resources to build modular, plug-and-play robots with CPS (cyber-physical systems) architecture. This links onboard electronics with cloud analytics to create adaptable ‘smart’ robots that can handle ambiguous real-world scenarios beyond controlled environments.
Sophisticated sensor systems with feedback loops and M2M communication protocols now allow robots to optimize tasks dynamically. There is also a push towards developing standardized operating systems that leverage open-source platforms like ROS 2.0 to accelerate autonomous robot deployment across industries. With falling costs and rapid progress in enabling technologies, 2024 might finally be the tipping point for intelligent robots.
- Scaling Up Renewable Energy and Storage
As sustainability concerns magnify globally, electrical engineers are increasingly shifting focus to advance renewable energy from proofs-of-concept to grid-level scalable systems. On the solar front, next-gen technologies like transparent solar panels, floating solar farms spanning reservoirs, and space-based solar power stations will start gaining traction.
However, the sun doesn’t always shine. So, wind and tidal energy offer complementary intermittent capacity. Additionally, research into novel battery designs using earth-abundant materials, solid-state electrolytes, and structural electrodes will unlock safer long-duration storage to overcome renewables’ Achilles heel. If these technologies cross economic viability thresholds, renewables are poised to dominate new power infrastructure worldwide by 2025.
- Embedding Electronics into Biological Systems
The intersections between electronic systems and biological processes provide fertile grounds for breakthrough innovations in medical technology. Advancements in materials, data science, micro-nano fabrication, and networks have expanded possibilities for building bioelectronic systems.
Key trends involve developing biocompatible customizable implants. Microsystem coatings like parylene chemically isolate delicate electronics within biological environments. Ingestible sensors and electrodes embedded in nerves can diagnose conditions or repair organ functions. Integrating electronics with tissues may also enable bionic body parts. DNA circuits allowing cells to perform Boolean logic opens doors for revolutionary diagnostics and drug delivery systems. This bioelectronic revolution will blossom in the coming decade.
- More Connected and Compact Power Systems
While electronics shrink in size, megapack lithium-ion batteries still occupy massive spaces. Now, experts envision integrated power foundations merging localized generation, distribution, and utilization components. Next-generation solid-state transformer equipment like GE’s AGILe will consolidate capabilities into compact, durable packages. Modular microreactors will also decentralize energy generation.
Likewise, structural supercapacitors and miniaturized antennas for over-the-air power delivery will revolutionize possibilities. Graphene, an exceptional conductor with immense strength, will transform wiring and charge-storing architectures. Ubiquitous 5G connectivity and the Internet of Energy Things will enable real-time control over power systems with unparalleled efficiency and reliability. Ultimately, integrated high-density power electronics foundations will catalyst future megacities and electrified transportation.
- Democratized Design and User Customization
Skyrocketing consumer appetite for personalized products is inspiring electrical engineers to develop toolkits allowing users to customize designs. Using configurators, people will choose from modular accessories and styling options to build tailored IoT devices, smart wearables, appliances, etc.
Democratizing design with embedded generators and 3D modeling templates will empower creativity. Makerspaces in local communities equipped with DIY electronics stations can drive grassroots innovation. Open-source programming modules and microprocessor daughterboards will also enable tinkering. Overall, these platforms herald an era of user-centric design and manufacturing for electrical goods.
- Testing and Certifying Safety for Next-gen Technologies
Engineers shoulder immense responsibility regarding public safety with electronics now embedded everywhere. However, evaluating risks for increasingly complex tech like autonomous robots requires new methodologies. Models checking corner cases using advanced neural networks and digital twin simulations will gain prominence. Setting reliability standards for bioelectronic implants needs multi-physics theoretical models considering chemical reactions and stress mechanics — an emerging field requiring cross-domain collaboration.
Likewise, renewables and green electronics usage at scaled levels involve environmental side-effects warranting investigation. Overall, the onus is now on researchers to pioneer science-based safety certification protocols for cutting-edge systems before market releases. Electrical engineers must champion evidence-based, standardized testing practices as sociotechnical landscapes evolve exponentially.
- Coping with Disruptions by Navigating Uncertainty
Looking towards 2024, electrical engineers stare at watershed moments as several next-gen technologies stand poised for breakthroughs. However, market dynamics evolve rapidly. So, disruptions like new substitute materials, shifting investment priorities, and broken supply chains warrant contingency planning.
Forecasting potential black swan events through scenario analysis is vital. Building organizational resilience by de-risking operations and strategically adapting is crucial. Training workers for disruptions via virtual simulations can help. Ultimately, hope for the best but prepare for uncertainty. Future-proofing the electrical engineering landscape to navigate the next normal calls for judicious decision-making under unpredictability.
