Miniature High-Voltage Power Supply and Miniature High-Voltage Controller

Featured Opportunity • Many microfluidics systems use electrokinetic (EK) pumping of fluid. These applications generally require high voltage at a low current. Sandia has developed two custom power supply designs with miniaturization, modularity, and scalability in mind. Each supply version is available in a variety of voltage ranges and polarities, with some ranges...

Miniature Spring Performance Tester

Featured Opportunity • Many systems require miniature coil-wound springs, such as firing devices, medical, and precision instruments. In order to qualify miniature springs, manufacturers of these systems rely on commercially available testers that are designed for large-scale springs (>0.5 in. diameter). Current state-of-the-art devices lack sufficient force resolution or cyclic test capabilities for...

Miniaturized Chemical Detectors for Point-of-Care Diagnosis

Featured Opportunity • Sandia’s mini-PDID makes it possible to diagnose illnesses by identifying volatile organic compounds (VOCs) associated with certain diseases and infections on a patient’s breath or in the headspace of biological fluids Building on decades of portable chemical analysis research, Sandia’s latest chemical detector, based on our miniaturized pulse-discharged ionization detector...

Miniaturized Mass Spectrometer

Featured Opportunity • Sandia has developed an improved quadrupole mass spectrometer (QMS). The improvement lies in the substitution of the conventional hot flament electron source with a cold cathode field emitter array (FEA), which in turn, allows the operations of a small QMS at much higher internal pressures then are currently achievable. By...

Miniaturized photoacoustic spectrometer

Patent • #9,410,931. A low-power miniaturized photoacoustic sensor uses an optical microphone made by semiconductor fabrication techniques, and optionally allows for all-optical communication to and from the sensor. This allows integration of the photoacoustic sensor into systems with special requirements, such as those that would be reactive in an electrical discharge condition....

Modification of electrical properties of topological insulators

Patent • #9,748,345. Ion implantation or deposition can be used to modify the bulk electrical properties of topological insulators. More particularly, ion implantation or deposition can be used to compensate for the non-zero bulk conductivity due to extrinsic charge carriers. The direct implantation of deposition/annealing of dopants allows better control over carrier...

Modular anti-rotation drilling systems and methods

Patent • #11,131,167. Drilling tools are frequently subject to rotation with respect to the central drilling axis caused by torque. A mechanical linkage can be configured to apply force that is proportional to the weight-on-bit on the borehole surface while transmitting axial loads used to generate weight-on-bit. The device can be used...
