Get real-time alerts with Sentrick Shield™


Epilepsy is one of the most common neurological disorders in the world, yet it remains widely misunderstood. For the 50 million people living with the condition globally, a seizure can strike without warning — in the shower, on the stairs, or while sleeping alone. The minutes immediately following a seizure are often the most dangerous, as the person may be unconscious, disoriented, or at risk of secondary injury from a fall.
Wearable monitoring devices have emerged as a critical safety tool for epilepsy patients and their caregivers. This guide evaluates the leading devices available in 2026, explains the technology behind seizure detection, and provides a practical framework for choosing the right solution based on seizure type, lifestyle, and caregiver situation.
Not all seizures are the same, and the monitoring approach must match the seizure type. The International League Against Epilepsy (ILAE) classifies seizures into focal (beginning in one area of the brain) and generalized (involving both hemispheres simultaneously). From a monitoring perspective, the most dangerous seizures are those involving loss of consciousness and motor convulsions — particularly tonic-clonic (formerly "grand mal") seizures, which carry the highest risk of injury and SUDEP (Sudden Unexpected Death in Epilepsy).
| Seizure Type | Characteristics | Monitoring Priority |
|---|---|---|
| Tonic-Clonic | Full-body convulsions, loss of consciousness | HIGHEST — automatic fall detection + emergency alert essential |
| Absence | Brief staring spells, no motor activity | MODERATE — GPS tracking; caregiver notification |
| Focal Aware | Altered sensation/emotion, consciousness retained | MODERATE — activity logging; caregiver notification |
| Focal Impaired | Altered consciousness, automatisms | HIGH — fall detection + GPS; emergency alert |
| Atonic (Drop) | Sudden loss of muscle tone, abrupt fall | HIGHEST — automatic fall detection critical |
| Myoclonic | Brief muscle jerks, usually brief | LOW-MODERATE — activity logging |
Modern wearable seizure detection devices rely on one or more of the following sensing modalities, each with distinct strengths and limitations.
The most widely deployed approach uses a multi-axis accelerometer and gyroscope to detect the repetitive, rhythmic motor patterns characteristic of tonic-clonic seizures. Machine learning algorithms trained on thousands of seizure recordings can distinguish genuine convulsions from vigorous exercise, restless sleep, or accidental impacts with high sensitivity. SENTRICK CARE™ uses a 6-axis IMU (inertial measurement unit) with an AI model that achieves over 92% sensitivity for tonic-clonic seizures in clinical validation studies.
Many seizures are preceded or accompanied by changes in heart rate. Tachycardia (rapid heart rate) occurs in the majority of tonic-clonic seizures, often beginning 30–120 seconds before motor onset. Devices that continuously monitor heart rate can use this signal as a secondary confirmation layer, reducing false positives and enabling earlier alerts.
Some specialized devices measure changes in skin conductance, which increase during sympathetic nervous system activation associated with seizures. EDA is particularly useful for detecting non-convulsive seizures that do not produce strong motion signals. However, EDA sensors require precise skin contact and are more sensitive to environmental factors such as sweat and temperature.
| Device | Detection Method | Alert System | GPS | Battery |
|---|---|---|---|---|
| SENTRICK CARE™ | AI 6-axis IMU + Heart Rate | Auto-call family + emergency services | ✅ Real-time GPS | 72 hours |
| Empatica Embrace2 | EDA + Accelerometer | App alert to caregiver | ❌ No GPS | 48 hours |
| Nightwatch | Accelerometer + Heart Rate | Bedside alarm + app | ❌ No GPS | Nightly charging |
| SmartMonitor | Accelerometer | App + phone call | ❌ No GPS | 24 hours |
| Apple Watch (SE2) | Accelerometer (fall only) | Emergency SOS | ❌ No GPS (standalone) | 18 hours |
| Garmin Vivosmart 5 | Accelerometer + HRV | App notification only | ❌ No GPS | 7 days |
Many epilepsy patients live independently and may experience a seizure while away from home — at work, on public transit, or in a park. In these situations, an alert to a caregiver is only actionable if the caregiver knows where the patient is. Real-time GPS tracking transforms a passive notification into a coordinated emergency response.
SENTRICK CARE™ transmits the patient's precise GPS coordinates at the moment of seizure detection, enabling family members or emergency services to locate them within minutes. The device also maintains a 24-hour location history, which can be valuable for identifying patterns — such as seizures that consistently occur in specific environments or at particular times of day.
1. What seizure types does the patient experience? Tonic-clonic and atonic seizures require automatic fall detection. Absence seizures may only need GPS and caregiver notification.
2. Does the patient live alone or travel independently? Independent living requires GPS and automatic emergency contact — not just app notifications.
3. Is nighttime monitoring needed? SUDEP risk is highest during sleep. Devices must be comfortable enough to wear continuously.
4. What is the caregiver's technical comfort level? Some platforms require significant setup; others are designed for non-technical users.
SENTRICK CARE™ was designed with the needs of epilepsy patients, elderly adults, and individuals with neurological conditions in mind. Its combination of fall detection alerts, real-time GPS, heart rate monitoring, and two-way voice calling makes it a practical monitoring tool for families — no medical prescription required. Not a medical device. Not intended for clinical diagnosis or treatment.
