Clinical Head

Biomedical Research Support

Clinical devices of the head

FBE, Flinders Biomedical Engineering, have developed devices for clinicians in the Flinders Medical Centre and the School of Medicine to assist monitoring of the eyes, brain and tongue.

Devices developed by Biomedical Engineering

CFFF Critical flicker fusion frequency

Device based on other publications to confirm good vision before cataract surgery undertaken [BME 1555]

EEG Response Keyboard

Purpose built keypad for human EEG studies to be undertaken by the EEG Research Unit at FMC. It has 11 keyboard keys and 2 fingertap pads. The fast response of the keypad with minimal known latency allows accurate correlation of the responses with EEG signals by the Presentation Stimulus Delivery program (Neurobehavioural Systems) [BME1459]

EEG Finger Tap Counter

The finger tap counter is designed to measure the rate at which a person can alternately tap their index and middle fingers on either hand, or both hands simultaneously. For each hand the patient has two finger pads on which to tap. The operator, who is in front of the patient, has access to the front panel displays and controls, which are not visible to the patient. Measurement is done by counting the number of taps over a period of time, which can range from one second to ninety nine seconds in one second increments. [BME1370]


Electropalatography (electrical palate recording of the palate) is an established technique for recording and analysing speech patterns. An oral palate is manufactured to fit a patient and fitted with 64 tiny electrodes for analysing speech patterns. This technique requires a custom made acrylic dental palate to be fitted with the tiny silver electrodes, wires, a coating and a connector. As the subject speaks, the timing and location of tongue contact with the palate is detected and the resulting signals can be interpreted through analysis software on a PC. [BME1436]
