Most of the current foetal heart rate monitoring devices are fabricated with hard materials that often discomfort the users. Furthermore, due to its rigid and bulky nature, it cannot be used for a long period of monitoring, nor can it conform to users of various sizes. Objectives are to examine soft biocompatible materials for the substrate, electrodes, and circuit, to develop a 3D printing wearable circuit which can effectively connect the electronic components, and to fabricate a functional prototype of the proposed wearable device.

Explore the breakthrough of additive manufacturing through constant research & development projects.
An adventure of 3D printing of Nitinol stent started in 2018 under a collaborative project between AM.NUS and Interplex Precision Technology (Singapore) Pte Ltd. This project aims to design and develop superior Nitinol stents using SLM technology that could meet medical requirements. The relationship between the 3D printing process (including powder preparation and post-process heat treatment) and Nitinol properties/microstructures are also being investigated.
