 Biomaterials
 Biomechanics
 Biosignals
 Biosystems
 Biotransport
 Clinical engineering
 Rehabilitation engineering

Work Fields (cont.)

Bioinstrumentation:
– Deals with principles and problems associated
with making measurements in living systems.

Biomaterials:
– Design and development of new materials
(natural and/or synthetic) to be used as
tissue, organ, drug delivery,….etc
Work Fields (cont.)

Biomechanics:
– Includes biofluid and biosolid mechanics at
molecular, cellular and organ-system levels.
(Example: ergonomics: design of chairs and
desks to reduce stress and injury.)

Biosignals:
– Use of data to uncover the mechanisms of
biomedical signals origin (Transform and
statistical techniques, chaotic analysis….
Work Fields (cont.)

Biosystems:
– Identify and characterise molecules and cells
and understand their function in tissues.

Biotransport:
– Covers transport processes from organ to
subcellular level (transport of ions, proteins,
viruses,….)
Work Fields (cont.)

Clinical Engineering:
– Deals with managing diagnostic and lab
equipment in hospitals.

Rehabilitation Engineering:
– Deals with disabled individuals to achieve
better standard of life by designing or
modifying new equipment (e.g. prosthetic
limb) for them.

The Need for bioinstrumentation
1. Scientific Method
In the scientific method, a hypothesis is tested by experiment to
determine its validity.
The Need for bioinstrumentation:
2- Clinical Diagnosis
The physician obtains the history, examines the patient, performs tests
to determine the diagnosis and prescribes treatment.
The Need for bioinstrumentation:
3- Feedback
A typical measurement system uses sensors to measure the variable, has
signal processing and display, and may provide feedback.
(a)
(b)
(a) Without the clinician, the patient may be operating in an ineffective
closed loop system.
(b) The clinician provides knowledge to provide an effective closed loop
system.
In some situations, a patient may monitor vital signs and notify a
clinician if abnormalities occur.
