This portfolio was organized to group innovations that might not be categorized in the other portfolios. Instruments are full systems integrated to perform complex electrical or mechanical work. Sensors are devices that detect, measure, or locate a physical property. Electronics are devices that manipulate electrons or control electrical energy, and the manufacturing processes that fabricate them.

Funded through DOE’s Unlocking Lasting Transformative Resiliency Advances by Faster Actuation of power Semiconductor Technologies (ULTRAFAST) program, LLNL researchers (in Engineering) will develop an optically-controlled semiconductor transistor to enable future grid control systems to accommodate higher voltage and current than state-of-the-art devices. (Award amount: $3,000,000) while LLNL licensee Opcondys will develop a light-controlled grid protection device to suppress destructive, sudden transient surges on the grid such as those caused by lightning and electromagnetic pulses. (Award amount: $3,178,977)
The Department of Energy’s Technology Transfer Working Group recently awarded two Lawrence Livermore National Laboratory (LLNL) employees with “Best in Class” awards during their May spring meeting in Washington, D.C.
A trio of LLNL scientists have been inducted into the laboratory's Entrepreneur's Hall of Fame. Each developed technologies during or after their Lab careers that created major economic impacts or spawned new companies.
LLNL researchers has developed designs to augment WBG/UWBG-based OALVs to improve their power handling capability under CW operational environments. These designs include:
Design and construction of a photoconductive switch requires a diamond photoconductor illuminated by light of a certain excitation wavelength. The diamond material is specifically doped with substitutional nitrogen, which act as a source of electrons. The device architecture allows maximum light entering the aperture. The top and bottom electrodes are made of ultra wide band gap (UWBG)…
The approach is to use a custom-designed frustrum and attach it to the optical fiber that connects to the PCSS. Light from the fiber enters the frustrum, spreads out, and enters the PCSS. Any unabsorbed light re-enters the frustrum and, because of its geometry, reflects back into the PCSS itself with only a negligible fraction escaping from the fiber. The shape of the novel frustrum is…
LLNL has developed a reference electrode that is a great improvement on the widely used silver or platinum wire QRE commonly used in electrochemistry in ionic liquids. This new reference electrode, based on a silver-sulfide coated silver wire, exhibits greatly improved stability over a QRE. The stability of our RE approaches that of the Ag/Ag+ RE, but unlike the Ag/Ag+ RE, the RE reported here…
The Optical Transconductance Varistor (OTV, formerly Opticondistor) overcomes depletion region voltage limitations by optically exciting wide bandgap materials in a compact package. A 100μm thick crystal could have the capability approaching 40kV and would replace numerous equivalent junction devices. Thus, unlike present junction transistors or diodes, this wide bandgap device can be stacked…
