What are military wearables?

Military wearables are electronic devices worn on the body that help soldiers navigate, stay healthy, detect threats and share information in the field. Unlike consumer fitness trackers, they are built to work under extreme conditions and are integrated into uniforms, vests, belts, helmets and other equipment. This article explains how they are used today, which types exist, what makes them hard to develop and where the technology is heading.

In short:

• Military wearables support navigation, health monitoring, threat warning, communication and training.
• Haptic (vibration) feedback lets soldiers receive information while keeping eyes, ears and hands free.
• The main challenges are ruggedness, signal quality on a moving body, battery life, weight and certification.
• The trend is towards fewer, integrated systems that interpret data on the body and warn the soldier directly.

How are wearables used in modern military operations?

Wearables are used wherever soldiers need information without stopping, looking at a screen or giving away their position. The main uses are:

• Navigation: haptic belts point the way with vibration, so soldiers do not need a lit screen or audio cues. Elitac’s Mission Navigation Belt was developed with the Dutch Ministry of Defence, won the Dutch Defence Innovation Competition in 2013, and its first series was delivered to the Royal Netherlands Army in 2020.
• Health monitoring and triage: biosensors track vital signs such as heart rate, respiration and temperature to detect heat stress, fatigue or injury early, and to support medics in the evacuation chain.
• Threat warning: wearables can warn soldiers of incoming threats, such as drones, and show the direction they come from.
• Communication and situational awareness: devices that support situational awareness, exchange data with command systems or show information through displays or augmented reality.
• Training: sensors that measure movement, physical load and performance during exercises.

The common goal: deliver the right information to the soldier with minimal distraction and risk.

What types of military wearables exist?

Military wearables can be grouped by their main function. Many advanced systems combine several of these.

Type	What it does	Example
Navigation and haptic feedback	Gives direction and alerts through vibration	Mission Navigation Belt
Threat warning	Detects threats and shows their direction	Haptic Drone Detection System
Physiological monitoring and triage	Measures vital signs of healthy or wounded soldiers	Soldier Health Patch, Flight Sense System
Smart textiles and protective wear	Integrates sensors and actuators in clothing and gear	Sensorised uniforms and load-carrying equipment
Communication and displays	Shares data with the team and command	Radios, wrist displays, AR headsets

Navigation and haptic feedback systems

These wearables give directional information through vibration instead of a screen. Small vibration motors around the waist or torso indicate direction, distance or alerts. They work on foot, in vehicles and on water, by day and by night.

Threat warning systems

Drones have made early warning on the body a priority. Elitac’s Haptic Drone Detection System uses helmet-mounted acoustic sensors to detect approaching drones and a haptic belt to let soldiers feel where the threat is coming from. Read more about haptic devices for drone threat warning.

Physiological monitoring and triage systems

Biosensor wearables measure signals such as ECG, respiration, skin temperature and movement. Dry, reusable electrodes help keep biosignal quality high during movement and reduce waste. Two examples:

• The Soldier Health Patch (MSEP), in development with the Dutch Ministry of Defence and partners, continuously measures five vital signs of wounded soldiers to automate monitoring and triage in the field.
• The Flight Sense System, developed with TNO, CML, 2M Engineering and the Dutch Ministry of Defence, measures ECG and respiration of fighter pilots with a washable belt with dry electrodes. It was tested in a T-38 jet trainer.

Smart textiles and protective wearables

Conductive yarns, printed electronics and modular connectors (see wearables integration techniques) allow sensors and actuators to be built into uniforms, body armour and load-carrying equipment. Applications range from posture and load monitoring to impact detection. The challenge is adding function without adding weight, stiffness or failure points.

What are the key technical challenges in developing military wearables?

Military wearables are harder to develop than consumer or even medical wearables. The main challenges:

• Ruggedness: devices must survive dust, water, temperature extremes, shock and vibration. Testing is often based on standards such as MIL-STD-810 and IP ratings. More in are military wearables waterproof and ruggedised?
• Signal quality on the move: motion artefacts disturb biosignals. Electrode choice, sensor placement and on-board signal processing must work together.
• Battery life: soldiers cannot always recharge in the field. Power must be optimised across hardware, firmware, sensor sampling and data transmission.
• Weight and integration: every gram counts, and the wearable must fit existing kit such as vests, belts, helmets and backpacks.
• Electromagnetic compatibility and security: devices must not interfere with other equipment (for example MIL-STD-461) and must keep emissions and data secure. See how military wearables communicate with command systems.
• Certification: requirements should shape design from the first prototype, not be addressed at the end. See our certification guidance.

How do haptic wearables improve soldier performance?

Haptic wearables deliver information through touch, leaving eyes and ears free for the environment. Attention is limited under stress, so every cue that does not need a screen or sound reduces cognitive load and helps soldiers react faster.

Tactile navigation is the most established use. A vibration on the left side intuitively means “go left”, so soldiers can follow a route without breaking stride, lowering their weapon or showing a light. That matters at night and when noise discipline is critical.

Haptics can also signal threat alerts, team status or equipment warnings, as long as patterns are simple and distinct enough to understand under physical and mental stress. That requires careful pattern design and user testing, not just a vibration motor.

The torso and waist are well suited for direction cues. Not because the skin there is especially sensitive (it is less sensitive than the hands), but because the body offers a large, natural 360° map: a vibration at a point on the body directly maps to a direction in space. Dutch research by TNO has long explored such tactile displays, including for pilots. Elitac works with CML (Centre for Man and Aviation) and TNO on haptic feedback for pilot training to support orientation in blackout and whiteout situations.

Which military domains use wearable technology most?

• Dismounted soldiers: hands-free navigation, threat warning, health monitoring and silent communication offer direct operational value.
• Military medical services: wearables support triage and continuous monitoring when casualties cannot be evacuated immediately.
• Aviation: pilots benefit from physiological monitoring and tactile cues for orientation.
• Training: wearables measure movement, physical load and fatigue to improve training and reduce injury risk.

Many European and North American defence organisations include wearables in their soldier modernisation programmes, often starting with pilots and field trials before wider roll-out.

What does the future of military wearable technology look like?

• Smarter on-body processing: algorithms that interpret data on the device and warn the soldier directly, for example for heat stress, fatigue or threats.
• Deeper textile integration: sensing and actuation built into fabric, so wearables look and feel like normal kit.
• Integrated multi-function systems: one system for haptics, biosensing and communication instead of several separate devices, reducing weight and failure points.
• Counter-drone awareness: wearable early warning for small drones is a fast-growing need.
• Interoperability: systems that connect with existing command and communication infrastructure and NATO partners.

The constraint stays the same: all of this must run on a small battery in harsh conditions, which makes firmware and power design as important as the sensors themselves.
