5. Fibre Biomedical Photonics
› Microstructured Polymer Optical Fibre
- Holes provide guiding, and sensitivity
› Unique capability at University of Sydney
› Inexpensive to access through ANFF
› PMMA (Perspex)
- Extremely low cost – disposable sensors
- Biocompatible / non-hazardous
› “Lab in fibre”
- Ultrasensitive molecular detection
- Picolitre volumes
- Long interaction lengths
› But also
- On Body (non-invasive), and
- In Body (invasive)
sensing / interfacing opportunities…
6. Fibre Biomedical Devices
› Non-invasive Sensing
- Fibre - sensitive to temperature, bending, pressure…
- Example: Heart rate monitor, integrated with PPE ->
- Potential: Fibre combined with bandage, could
provide long term, continuous, inexpensive pressure
monitoring, including remotely.
- Also monitor heart-rate, blood pressure, or physical exertion.
› Invasive Interfacing
- Neural interface – channels for:
- Electrical: detection and stimulation
- Chemical: drug delivery
- Optical: optogenetic detection and stimulation
- Developed for neuroscience research
