Course description

Wearable sensor technology, particularly inertial measurement sensors are used in various motion analysis including applications in sport, medicine, and rehabilitation of patients after stroke. However, how would a hemiparetic stroke patient mount a sensor?
In this project, we aim to design and build a prototype to self-attach a wrist-worn sensor using 3D printing technology. In particular, we aim to develop a sensor applicator which allows users to self-attach and remove a wristband with an integrated motion sensor, in an automatic self-guided process. In addition, the sensor applicator should offer to recharge the wristband, similar to a charging station for a smartphone. We will evaluate and demonstrate the feasibility of the sensor applicator prototype.

Learning objectives

  • Learning design principles in an engineering project.
  • Defining design requirements and propose solutions for sensor applicator.
  • Developing a 3D CAD model and construct a prototype of a sensor applicator.
  • Gain practical experience in an engineering project.
  • Teamwork.
