- Gravity sensing has been identified as one of the "Grand Challenges" of the UK's National Quantum Technology Programme. This work presents the general design framework for the topology of micromachined gravity-gradient sensors demonstrating the concept of one such topology, a torque sensor with an angular flexure. This led to collaboration with Qinetiq to develop gravity mapping sensors(contact: FoEREF@ic.ac.uk) and inclusion of Imperial in the UK's Quantum Sensors Hub for hybrid MEMS/cold-atom instruments for gravity sensing and the search for dark matter where the silicon sensor will remove ambient seismic injection on the quantum interference pathway of the cold atoms
