Can Biosignal Sensors Be Used on Children and Infants?

Biosignal sensors play an important role in monitoring physiological activity in every age group — children and infants included. Thanks to advances in technology, many sensors are now designed to be safe, adaptable and effective for paediatric use.

Why use them on children and infants?

Monitoring physiological signals in children and infants is critical for the early detection of developmental problems, neurological conditions or heart rhythm irregularities. Paediatric applications often call for non-invasive, highly sensitive and miniaturised solutions.

Sensors suited to paediatrics

Functional near-infrared spectroscopy (fNIRS)

Use

Brain monitoring for developmental studies; oxygenation levels in infants with neurological conditions.

Why it is ideal

It is non-invasive and gentle; suited to real-time monitoring without causing discomfort.

Photoplethysmography (PPG)

Use

Heart rate and oxygen saturation in newborns; sleep studies assessing respiratory and cardiovascular health.

Why it is ideal

Its compact design attaches easily to a finger or toe; safe and comfortable for continuous monitoring.

Electroencephalography (EEG)

Use

Brain activity in premature infants or those at risk of seizures; research into cognitive and neurological development.

Why it is ideal

Electrodes and caps that fit small head sizes; safe use with low-intensity signals.

What to consider in paediatric monitoring

Comfort

Sensors should be light and flexible and sit on small anatomies without causing discomfort.

Non-invasive

Avoiding invasive procedures makes for stress-free monitoring.

Sensitivity

More sensitive sensors are needed to capture subtle signals.

Durability

Sensors must be durable enough to withstand infants’ movement.

Conclusion

Biosignal sensors are safe and highly effective in children and infants, providing critical information about health and development. From fNIRS to PPG and EEG, these technologies are designed to prioritise safety, comfort and accuracy. With the right paediatric-friendly sensors, clinicians and researchers can reach meaningful results while ensuring a positive experience for young patients.

Any physiological monitoring of infants and children should be carried out under the supervision of the relevant health professional and with appropriate protocols.
