By utilizing the highly sensitive accelerometers within millions of consumer devices, the system measures the natural frequencies and damping ratios of buildings through ambient vibrations. This crowdsourced data provides a real-time, large-scale assessment of structural health across entire urban environments. The platform effectively transforms everyday mobile devices into a distributed seismic monitoring array, allowing for continuous observation of building performance without the need for dedicated hardware installations.

Developing robotic hands that can safely and effectively grasp a wide variety of objects remains a significant challenge, often requiring heavy motors and complex sensor arrays.

By utilizing underactuation—where a single motor drives multiple degrees of freedom—the design achieves high dexterity with minimal mechanical complexity. The CMC joint is engineered to respond passively to contact forces, allowing the fingers to wrap around objects of varying shapes and sizes automatically. This innovation enables a natural, compliant grip that mimics human hand mechanics, providing a lightweight and cost-effective solution for advanced manipulation.

The implementation of cost-effective and reliable energy storage solutions, such as redox flow batteries, is often hindered by the complexity and expense of accurately monitoring their state of charge (SOC) and state of health (SOH). To address this, a novel approach using low-cost management systems and methods has been developed for electrochemical cells based on viologen, particularly pyridinium redox flow batteries. This innovation centers on pH signaling and regulation to enable real-time SOC and SOH monitoring. The viologen species' electrochemical processes naturally induce localized pH changes, and by monitoring and regulating the pH within the cell, researchers can obtain immediate, actionable data on the battery's operating condition. This pH-based system offers a simple, integrated, and economical alternative to conventional, often more complex, monitoring techniques.

The deployment of robotic systems in real-world environments is often limited by the "sim-to-real gap," where policies trained in digital simulations fail to account for the complex, multisensory feedback of physical reality. Researchers at UC Berkeley have developed a novel method for training multimodal sim-to-real robot policies by integrating generative audio models with traditional physics-based simulators. This framework uses a generative model to synthesize realistic audio data that corresponds to simulated physical interactions, creating a rich, multimodal dataset for policy learning. By training on both simulated physics and generated sensory data, the system enables robots to develop more robust and adaptive behaviors that translate seamlessly from virtual training environments to complex real-world tasks.

         Dust accumulation on solar panels, particularly in desert regions, can cause significant power losses without frequent water-based cleaning. With the global solar capacity rising, current cleaning methods yield high operational costs, consume billions of gallons of water annually, and pose sustainability and resource challenges.         To overcome these challenges, UC Berkeley researchers have developed a passive anti-soiling coating, which can effectively repel dust particles without energy or resources. The anti-soiling performance can be triggered by an onset temperature as low as 40 °C—common in most operating environments—and has been demonstrated to repel nearly all dust particles in preliminary studies. The approach is practical and highly promising for large-scale deployment.

Traditional imaging techniques often rely on bulky hardware or complex computational methods to resolve depth. UC Berkeley researchers have developed a three-dimensional imaging system that utilizes piezoelectric micromachined ultrasound transducers to capture high-resolution spatial data with an integrated approach that allows for compact, high-performance imaging that can be used in a variety of environments where traditional optical or radar systems might be limited.

Traditional 3D printing methods rely on layer-by-layer deposition, which often limits speed and introduces structural weaknesses. Computed Axial Lithography (CAL) revolutionized the field by using projected light to cure entire volumes at once, but it was previously constrained by the size of the illumination field. UC Berkeley researchers have advanced this technology with a Helical Cone Beam CAL system. By combining a rotating target volume with a synchronized translation mechanism, the system projects patterned cone beams in a helical path through radiation-reactive material. This allows for continuous printing of much larger objects than traditional CAL and even enables "inner printing"—the fabrication of new structures inside or around existing solid objects.

      The widespread occurrence of nutrient-rich and metal-contaminated wastewater presents an environmental challenge and untapped economic opportunity. Ammonia, copper, and phosphorous are prime targets. For example, ammonia is industrially produced by the Haber-Bosch process, a highly energy-intensive (~12.5 kWh/kg-N to convert N2 to ammonia, consuming 1-2% of global energy usage) and greenhouse gas-emitting (~1.2% of global CO2 emissions) technique. After use, primarily as fertilizer, nearly 50% of all U.S.-consumed ammonia ends up in municipal wastewater and animal feedlot retention systems. Technologies presently proposed for recovering critical nutrients and metals from wastewater are limited in scalability by high energy demands, costly chemicals or membrane requirements, low efficiencies, or fouling challenges.       UC Berkeley researchers have developed and demonstrated a low-cost, robust, and near-zero-energy reactor that simultaneously recovers ammonia and other valuable ions (e.g., P and Cu) from wastewater streams. The reactor is driven by sunlight or low-grade waste heat, such that it eliminates the need for external pumping—further cutting energy consumption and capital cost. The functional material is an inexpensive cloth that is also roll-to-roll compatible, making it economically scalable and easy to manufacture. The reactor can be implemented within wastewater streams including municipal wastewater, animal feedlot wastewater, and organic waste digestate. It may further be adapted to recover other valuable resources, such as lithium, from sources like mining wastewater and landfill leachate. It may even be extended beyond nutrient and metal recovery to separation or pre-concentration of volatile organic compounds such as ethanol and methanol from aqueous solutions.

Traditional environmental policymaking often struggles to efficiently target interventions to achieve multiple, complex air quality goals simultaneously across a geographic area. This innovation, developed by UC Berkeley researchers, addresses this challenge by providing a sophisticated, multi-objective optimization method for targeted reduction of air pollution. The method generates a comprehensive mitigation pathway by integrating several modules: a forward module to model pollutant concentrations, a target concentration surface that defines the policy goals, a prioritization module to assess uncertainty and importance via a prioritization covariance matrix, and a Bayesian inversion module to estimate optimum emissions required to meet the target. This systematic, data-driven approach culminates in a mitigation pathway that guides the performance of specific pollution control measures, offering a significant advantage over conventional, less targeted policy-making by ensuring resources are directed where they will have the maximum environmental impact.

UC Berkeley researchers have developed a novel dispersion system for agricultural and environmental payloads, including seeds, soil amendments, miniature soil sensors, and so forth. Dispersive packages are biodegradable and biomimetically designed with similarities to natural seeds. Aerodynamic properties control large-area dispersions, while importantly, tunable gyroscopic properties are programmed for penetration parameters, such as depth, upon impact. Payload distribution can be fine-tuned accounting for local soil moisture and grain-size.

Current sustainable building materials often lack the high structural strength needed for demanding applications, limiting their use in load-bearing construction. Addressing this opportunity, UC Berkeley researchers have developed SEA-BOARD, a novel structural panel fabricated from marine-derived polysaccharides. This innovation utilizes a proprietary, stepwise process involving polysaccharide extraction, nanofiber alignment, and thermal densification to configure the macroalgal biomass into a high-strength, hot-pressed panel. This engineered material is structurally superior and potentially more environmentally sustainable than many traditional wood-based or synthetic alternatives.

High-conversion-ratio power converters used in compact Point-of-Load (PoL) applications, such as data centers or portable electronics, often face the challenge of large size and weight due to the necessary energy-storage components, particularly flying capacitors, while also struggling with switching losses that reduce efficiency. This innovation, developed by UC Berkeley researchers, addresses these issues with a novel regulating hybrid switched-capacitor (HSC) power converter topology referred to as a "Dual Inductor Switching Bus Converter" (DISB converter). The DISB converter combines an initial 2:1 switched-capacitor conversion stage with a Symmetric Dual-Inductor Hybrid (SDIH) conversion stage, capitalizing on the benefits of both. The initial 2:1 voltage reduction significantly reduces the overall volume and weight of the flying capacitors, while the SDIH stage contributes a reduced component count and an excellent switch stress figure of merit. Crucially, a proposed auxiliary circuit block enables near-zero-voltage conditions (partial soft-switching) within the initial 2:1 stage, which significantly improves the converter's overall efficiency.
