A simple two-mode resonant circuit is presented for the first time which forms the basis for ultra-low noise and high linear dynamic range capacitive sensing solutions operating at room temperature and potentially in elevated temperature environments. The circuit is configured so that the transfer function is a close approximation to an All-Pass Filter architecture that minimises the effects of AM conversion. Effectively it represents an almost pure and cost-effective single-ship capacitance-to-phase converter. It can be incorporated into well-known, carrier phase noise cancelling, ultra-sensitive read-out schemes such as interferometers, flip-flops and lock-in amplifiers (US Patent Applications 17988033, 18230348). If used as a properly tuned moving-plate displacement-to-phase converter, the predicted position noise is about 3 femtometre/√Hz and no other room temperature capacitive displacement transducer has matched this performance. This capacitive sensing solution has been successfully incorporated into a new version of TAIPAN Gravity Gradiometer which was tested recently in a harsh outback environment in Western Australia. The results of this field test will be published elsewhere.
Trinity Research Lab jointly with Lockheed Martin Corporation (USA) have published a research article in Nature Scientific Reports describing the physical background of the TAIPAN gravity gradiometer development (https://www.nature.com/articles/s41598-022-11232-6).
Queen Elizabeth II passed away on September 8, 2022, at the age of 96. She is now being reunited with Her beloved husband Prince Philip, Duke of Edinburgh, who was mystically curious about gravity gradiometry once upon a time.
The Queen is dead, long live the King.
Trinity Research Lab was invited to participate in the latest Australia Defence Innovation Hub meeting on June 28, 2022. The purpose of the meeting was to invite industry representatives to join Australian Defence Forces experts in a major effort to upgrade national defence capabilities. One of the critical technological developments mentioned during the meeting was integrated Undersea Surveillance Systems. Trinity Research Lab in collaboration with the QDM Lab has the ability to make a significant contribution to this effort. The detection of nuclear armed submarines is one of the most important problems in the modern world, especially taking into account recent military adventurism in Europe and Asia-Pacific.
Sadly, the war in Ukraine continues and the vast majority of normal human beings want Ukraine and its global supporters to crash the reincarnated "Third Reich".
Trinity Research Labs and Lockheed Martin have entered a critical stage in developing a field deployable prototype of the TAIPAN Gravity Gradiometer module. The testing is scheduled for mid September 2022 at a WA outback area where land-based gravity measurements have been conducted and the data sets are available for comparison.
A joint paper ( Trinity/QDM and Lockheed Martin Gravity Systems ) "Static and Dynamic Analyses of Free-Hinged-Hinged-Hinged-Free Beam in Non-Homogeneous Gravitational Field: Application to Gravity Gradiometry" has been accepted for publication in Nature Scientific Reports.
Sorry, the New Year is not any better. In fact much worse. Sad news - Russia invaded Ukraine as a result of the pseudo-imperial madness that is dominant now among the russian ruling elite. A famous German physicist (Sommerfeld) wrote to Einstein shortly after Hitler took power: "I can assure you that the misuse of the word ‘national’ by our rulers has thoroughly broken me of the habit of national feelings that was so pronounced in my case. I would now be willing to see Germany disappear as a power and merge into a pacified Europe". That what it is now. Sure, Russia will follow, sooner or later, and those who are responsible for this madness will be punished severely for their actions.
Happy Christmas to everyone and a better New Year ahead.

This book provides readers with a comprehensive and updated overview of the history, applications, and current developments in relation to some of the most advanced technologies in the 21st Century, especially regarding future challenges in natural resource exploration in the changing energy supply environment and a post COVID world. This new edition incorporates the most important new directions bringing fresh ideas into the field, including quantum or quantum-enabled sensing and miniaturization of the operational environment in which gradiometers should function.
A New Edition of the book ( both eBook and print versions ) titled "Gravity, Magnetic and Electromagnetic Gradiometry: Strategic Technologies in the 21st Century" is now being drafted to be published in 2021 as per an agreement signed with the Institute Of Physics Publishing (IoP, UK). There have been ~ 9000 downloads in 52 countries since the former Edition was published in 2018.
More good news from our Breast Cancer Research Project. The clinical tests conducted at the Harry Perkins Medical Research Institute have been successfully accomplished and the data collected from ten clinical cases are now being post-processed and visualised.
Trinity Research Labs (TRL) is grateful to the Federal Government of Australia for establishing the Job Keeper financial support scheme that has allowed us to continue our advanced development projects. Lockheed Martin (USA) has confirmed its willing to continue supporting the TAIPAN Gravity Gradiometer technology development that was greatly reduced in intensity due to the Coronavirus COVID-19 Pandemic. The TAIPAN technology is now being prepared for field testing as travel restrictions within the state of Western Australia have been removed. More good news is that our Breast Cancer Research Project has been resumed, taking advantage of the removal of restrictions on clinical test measurements at the Harry Perkins Medical Research Institute in Perth (WA) on human tissue samples. To date encouraging results have been received from five clinical cases, details of which will be reported publicly later in 2020.
Trinity Research Labs (TRL) has ceased it's R&D activities at the Physics Department of the University of Western Australia from March 2020. This action has been taken in light of measures introduced recently in Australia and in the State of Western Australia in the battle against the Coronavirus (COVID-19). Let the Force be with us.
As of May 2019 Trinity Research Labs is an official qualified Vendor to Lockheed Martin Corporation (LMC, USA), collaborating on a new gravity gradient sensing methodology. The “TAIPAN” Project is being co-developed with the Gravity Systems line of business within LMC’s Rotary and Mission Systems Division. Recent prototypes have proved the measurement capability in a laboratory environment, and now a self-contained portable (e.g. hand-carried) advanced development model (ADM) is ready for field tests. The sensitive element of the new TAIPAN instrument is a compliant metal ribbon-like strip that deforms in a known way in response to gravity and its gradients. These extremely tiny deformations are measured with a first-of-its-kind non-resonant phase sensitive capacitive metrology capable of measuring mechanical displacements all the way down to just 10’s of femtometres. This amazing new capacitive gauging has broad applicability just as the commonly used capacitive sensors do today, and should open the door to a multitude of new transducers and actuators in a variety of scientific and manufacturing industries.
A book ( both eBook and print versions ) titled "Gravity, Magnetic and Electromagnetic Gradiometry: Strategic Technologies in the 21st Century" has been published by the Institute Of Physics Publishing (IOP, UK) and Morgan & Claypool (USA). This is the first accumulative book published on this difficult topic: http://iopscience.iop.org/bookListInfo/iop-concise-physics
Trinity Research Labs, jointly with the Frequency Standards and Quantum Metrology Group of the University Of Western Australia, have patented a new Intrinsic Gravity Gradiometer. The Gradiometer is the next step in developing ultra-sensitive pocket-sized room temperature operating Gravity Gradiometers that are capable of being deployed in drilled wells and unmanned moving platforms, including airborne, marine and submersibles. Currently, the project "TAIPAN" ( the nickname of the Gravity Gradiometer under development ) is underway aimed at the manufacturing of a fully operational prototype Gravity Gradiometer later in 2017. The project is fully funded by one of the UWA industry partners.
Trinity Research Labs, jointly with the QEII Medical Research Centre; the UWA Medical Physics Group; the UWA School of Electrical, Electronic and Computer Engineering; and the UWA School of Surgery, have won a National Breast Cancer Foundation Grant (two years funding). The project commences in January 2017 and is aimed at the development of a low-risk, low-cost, non-invasive high-sensitivity method of early breast cancer detection based on electromagnetic gradiometry. The technology has been developed by the Trinity Research Labs as a new technique for mineral exploration and defence related applications. Later, it has been realised that the technique has a potential for the detection of cancerous cells which manifest themselves as anomalously conductive breast tissue.
