Coastal inlets and river mouths create dynamic, unpredictable environmental conditions that make it difficult to plan surface and subsurface ocean operations.
the ARM-H robotic hand
SRI and partners are developing highly dexterous low-cost robotic hands for military applications and other real-world uses.
researcher analyzing biocrude oil
An SRI-led team is improving a new two-step process for the production of transportation fuels from microalgae.
row of vials containing glowing material
In a nuclear or radiological incident, first responders must quickly measure the radiation exposure of a large number of individuals, since treatment options are radiation dose-dependent and time-sensitive. SRI is developing a biodosimeter to meet this critical challenge.
power plant
SRI's process produces pure hydrogen while capturing carbon dioxide and acid gases.
artist's rendering of a lump of coal with black oil dripping from it
SRI has developed a green, cost-effective approach to create liquid fuels from existing natural resources.
SRI provides high-fidelity computational fluid dynamics (CFD) analysis and comprehensive physics-based system multibody dynamics (MBD) modeling
SRI's proof-of-concept system
SRI is developing a safe, low-pressure, conformable natural gas tank for light-duty vehicles.

SRI is developing a novel point-of-care tool for the early detection of devastating diseases.
Estimation of River Characteristics from Remote Sensing Data.
SRI's falling-bead reactor
SRI’s carbon capture system can make economic sense today at facilities that produce and consume carbon dioxide.
Together with GexCon US, SRI is designing and conducting experiments to improve and validate tools used to minimize the risk of explosions or fires on offshore platforms.
An SRI researcher observes FRASTA images on a computer
SRI has developed a breakthrough technology for diagnosing and predicting fatigue failure in pipelines, aircraft, bridges, power plants, and other structures using quantitative 3D fractography.
Micro-cylindrical ion trap arrays
SRI is developing small, highly sensitive arrays for pervasive monitoring of chemical and biological processes in the ocean and other environments.
hollow fiber membrane being inserted into a pressure value
SRI’s hollow fiber membrane separates hydrogen from carbon dioxide at high temperatures and improves the economics of carbon capture from IGCC plants.
canisters of hydrogen stacked up next to a flammability warning sign
SRI has partnered with Sandia National Laboratories to provide the data necessary to ensure that hydrogen can be used safely as a transportation fuel.
A novel, ultra-compact variable transmission promises to dramatically increase efficiency for robotics systems and allow for safer human-robot interaction.
SRI is developing new technology to reliably control thousands of micro-robots for smart manufacturing of macro-scale products in compact, integrated systems.

SRI researcher working on SRI's mixed- salt process
SRI’s mixed salt process uses known solvents in a new way to dramatically improve the economics of carbon capture.
SRI combines data assimilation algorithms with hydrodynamic forecast models for high-resolution forecasts of nearshore oceanographic properties for coastal operations. 
Three SRI researchers working on the wearable thermal management technology
SRI is developing a system to manage a person's heating and cooling individually, saving energy by not overheating or overcooling areas within a building where the person is not present.
gloved hand inserting a cartridge into the sentinel device
From raw sample to molecular results in minutes: The Sentinel Nucleic Acid Analysis System offers portable, real-time diagnosis of health conditions.
Two SRI researchers work on a RAX CubeSat
