SPATIUM team

The Micro-sensors team specializes in sensors’ design, fabrication, packaging, testing and implementation.

Over the years, the team partners with various faculties from different engineering schools in NTU to build up the basic foundation technology blocks, like Deep Reactive Ion Etching capabilities and Micro-Electro-Mechanical Systems (MEMS) wafer level 3D packaging. These technologies were eventually translated to local MEMS foundries for large scale production.

From 2014 onwards, the team has embarked on the next stage of growth using different sensors technology for various miniaturized product development in several on-going and upcoming projects. One such application is sensors on robots for indoor mapping and development of various strategies for indoor location tracking.

Miniaturized MEMS sensors
– From university laboratories to foundries
Long distance identification tracker system with open field line of sight
High resolution indoor mapping solutions
Innovative indoor and outdoor high resolution tracking system

The Micro-sensors team has developed an innovative solution of packaging the Chip Scale Atomic Clock (CSAC) to operate in the harshest environment in the Low Earth Orbit (LEO). This was successfully demonstrated in NTU’s satellite SPATIUM-1 which was orbiting since October 2018.

For the past few years, the team is providing high resolution indoor navigation mapping for the annual NTU Open House event. This is a marriage of several key sensors technologies.

In 2015, the team has developed a miniaturized identification wearable system. It was brought to field demonstration of over 2.5 kilometers of stand-off in open field light of sight. This miniaturized system has the potential of being applied to advanced robotics and navigation.​​​​​​​​​​​​​​​
