Main Equipment
  • Modelling Softwares: COMSOL Multiphysics, MAXWELL ANSOFT 2D/3D, MATLAB, OOMMF
  • Clean room MEMS/NEMS fabrication facilities
  • Clean room sophisticated pulse reverse electroplating facilities
  • Bruel & Kjaer shaker, wideband digital oscilloscope and control loop software
  • SQUID magnetometer with Liquid He temperature platform
  • Wide-band (1MHz to 10GHz) permeameter for complex permeability spectra
Typical applications
Micropower systems and nanomagnetics group within Tyndall National Institute is primarily involved in the design, modelling and development of next generation, meso- to micro- scale (MEMS to NEMS) powering devices for tiny autonomous sensor node enabling a smart and responsive environment around us, essentially for realisation of the Internet of Things – IoT
Case Study
An SME or research team who are developing new MEMS/NEMS structures, relevant materials for micro/nano scale energy harvesting devices and need access to modelling, fabrications and characterisation equipment to optimise their devices can get access through EnABLES to the facilities required. A typical project will offer 15 days access to the Tyndall researchers and equipment required.
