Arsha Beena Kumary is a PhD researcher in I-Form based in Dublin City University working in the area of Shape Memory Alloy (SMA) characterisation. She completed her undergraduate degree in Physics from University College, India and then pursued her Masters in Physics with specialization in applied electronics from Kerala University, India. Her main research interests are in the areas of SMA-based material development, property analysis and post processing study.
Technical Summary
The main focus of this research is to address challenges associated with SMA based materials, such as fatigue, large hysteresis, slow response, etc. The objective is to obtain a deeper understanding of physical properties and material science using thin films of NiTi-based SMAs. This understanding is crucial for optimizing the properties of NiTi-based SMAs, post-processing, designing new SMAs, and applying this knowledge in advanced manufacturing and device fabrication.
The project is focussing on developing strategies to grow NiTi based SMA thin films using a plasma based physical vapour deposition technique which can tailor the properties by controlling the parameters. The study also aims to understand the effect of post-deposition techniques and treatments on the functional properties of SMA films. The ultimate aim is to explore the possibility of using these films in applications in one or more areas such as MEMS (Micro-Electro-Mechanical System), flexible/wearable electronics, and the biomedical field.
