Analytica Ltd

Return to List

Closed Posted: 26 Jun 20. Closes: 08 Jul 20 Available: Semester 2 (Jul - Nov)

UPDATE 20/7: a student has been appointed to this project.

Semester 2 2020 project

UQ Engineering students only (ENGG4011 thesis or Masters project)

This thesis project is for a UQ final year student in Mechanical or Biomedical Engineering with an interest in medical device development, mechanical force application, and physical (ME) design.

The successful applicant will receive a $3,000 scholarship + academic credit for enrolment/assessment (6 unit final year thesis ENGG4011 / 4 unit Masters project).  You must be available to work on the project onsite for 3-4 days/week during Semester 2 2020 (around lecture timetable). 

APPLICANTS NOTE: upload your resume with unofficial academic transcript/s (undergrad + Masters if applicable - combined into 1 doc/pdf). Also include your student ID number. Upload resume before OR after applying for project/s.  

UQ ELIGIBILITY REQUIREMENT: all CEED applicants must get a written study plan approved (by a UQ academic advisor) which shows thesis/project unit enrolment is possible for Semester 2 2020.

We cannot progress your application until you provide this info to CEED (please email to CEED before the project's application close date). Advise CEED if you need assistance or are experiencing delays in receiving an approved study plan.

Project Background / Description

Analytica's lead product, the PeriCoach, comprises of an insertable probe with force sensors that detect the applied force of the female users' pelvic floor as it squeezes against the probe, and a Smartphone app that connects via Bluetooth to the probe to provide a visual output of the pelvic floor activity.

Because the force sensors (FSRs) are a critical part of the product, we are always seeking ways to enhance their performance - make them more accurate, more repeatable. 

We have a single supplier of high quality FSRs which is a risk to the company, and a second supplier has been identified but their product quality is not as good. 

This project is aimed at exploring ways to enhance the performance of the second supplier's sensor from a mechanical perspective (eg: force directing through profile changes of the silicone sheath or underlying body).  This experimental investigation will inform the potential improvement of the current sensors as well.


Analytica Limited is a Brisbane-based public company listed on the Australian Stock Exchange. The company is dedicated to the design, development and supply of Class I and II medical devices.

Objectives / Tasks / Project Outcomes

Perform investigation to:

  • Work with FSR manufacturers and perform research to understand how an FSR works
  • Propose ways to enhance performance using the mechanical structure of the probe
  • Carry out experiments accordingly using prototypes and jigs as appropriate.  This may involve collaborating with the manufacturer.
  • Report on outcomes and provide recommendations from findings

Skills / Experience Required

  • Thorough understanding of mechanical engineering concepts.
  • Good understanding of electronic concepts (need to understand the electronic aspects of the sensor and its outputs, but it will be mainly mechanical application of force)
  • Interest in medical device design and development
  • Ability to think creatively to design and develope test jigs.
  • Ability to work autonomously, with regular communication and support from company supervisor (qualified Engineer), as the project is work from home basis
  • Very good communication (oral, written) and time management skills

  • This project would be ideal for a female Engineering student (if possible) - due to the type of medical device and testing needed.
