Various types of biosensors used in healthacare

1. A sensor is a device, module,
machine, or subsystem whose
purpose is to detect events or
changes in its environment and
send the information to other
electronics, frequently a computer
processor

2. TEMPERATURE SENSOR
A temperature sensor is an electronic device that measures the temperature of the body and converts the input data into
electronic data to record, monitor, or signal temperature changes
(sensing
signal to
analog
voltage)
Patient monitoring, temperature logging,
fluid temperature, warming blanket

6. ULTRASONIC SENSOR
➢ Abdomen diagnosis
➢ Mammary and thyroid glands diagnosis
➢ Cardiology diagnosis
➢ Transvaginal and transrectal diagnosis

7. Air Bubble Detectors
- detect the presence of bubbles in fluid filled tubes
Extracorporeal Blood Circuits
Ultrasonic sensors

8. Electrocardiogram sensor
It measures the electrical activity of the heart
→records the pathway of electrical impulses through the heart muscle, and
can be recorded on resting and ambulatory subjects, or during exercise to
provide information on the heart's response to physical exertion.

9. Electroencephalogram sensor
Small electrodes and wires are attached to your head. The electrodes detect your
brain waves and the EEG machine amplifies the signals and records them in a
wave pattern on graph paper or a computer screen

10. Electromyography Sensor (EMG)
An electromyogram (EMG) measures the electrical activity of muscles at rest and during contraction.
---This sensor will measure the filtered and rectified electrical activity of a muscle, depending the amount of
activity in the selected muscle.
