How eBand Uses Real-Time Biometrics to Personalize Smoking Cessation

Quitting smoking remains one of the hardest health challenges for millions of people around the world. Traditional nicotine replacement therapies often lack adaptability, fail to respond to withdrawal symptoms in real-time, and require strong willpower to maintain consistency. The eBand changes this approach completely. This innovative wearable device detects physiological signs of withdrawal and delivers nicotine or bupropion precisely when needed. It adapts to the user's condition throughout the quitting process. With carbon nanotube technology and sensor-driven therapy, eBand offers an intelligent and gradual path to recovery, helping users regain control over their habits with fewer side effects and setbacks.

Monitoring Withdrawal through Biometric Signals

The eBand relies on two physiological indicators to detect withdrawal symptoms: changes in blood pressure and skin conductance. These signs have been scientifically linked to nicotine cravings and stress. By continuously measuring these metrics, the device can detect early withdrawal symptoms before they become overwhelming. A photonic integrated circuit (PIC) and laser Doppler vibrometer (LDV) are used to measure blood pressure variability. These components make it possible to capture data without direct contact, ensuring comfort and precision.

At the same time, skin conductance is measured using bipolar recording across two skin electrodes. These sensors detect changes in electrical conductance caused by sweat gland activity, which rises during stress. Together, these two indicators create a complete physiological profile, allowing the system to determine if the body is entering a withdrawal state. Once confirmed, the device calculates whether medication should be released and how much should be administered. This real-time tracking helps prevent major cravings while reducing unnecessary exposure to nicotine.

Nanotube Technology for Targeted Medication Release

The most innovative part of the eBand is its medication delivery method. Unlike nicotine patches or oral gum, the eBand uses Multiwalled Carbon Nanotubes (MWCT) to control the release through nanochannels. These nanotubes carry medication in liquid form and deliver it directly to the skin when an electric current is applied. The cartridge inside the device holds a small dose of nicotine or bupropion and remains sealed until triggered by biometric data.

When withdrawal symptoms are detected, a voltage of 1.7 volts is applied between the cartridge membrane and an internal platinum wire. This creates a switch in the liquid’s surface properties, allowing a measured droplet to flow through the nanochannels and onto the skin, where it is absorbed. This process is fast, clean, and dose-controlled. As the user progresses through their recovery, the amount of medication delivered is gradually reduced, helping the body adapt to lower nicotine levels naturally. The eBand does not rely on timers or estimates—it responds only when the user truly needs support.

Personalized Therapy and Progress Tracking

The eBand is designed to do more than deliver medication—it helps users understand and manage their progress. It connects to a smartphone application via Bluetooth, which allows the user to view real-time stress levels, monitor nicotine use, and adjust their preferences. The app logs dose, response, and physiological changes. This feedback helps users become more engaged with their recovery journey and recognize the moments when their body is improving.

Over time, as withdrawal symptoms decrease, the system adjusts automatically to reduce medication output. This gradual decrease supports long-term nicotine independence and improves your chances of staying smoke-free. In addition, the smart algorithm prevents misuse by blocking delivery when it is not needed. The device is compatible with both nicotine and bupropion cartridges, giving users and healthcare providers more flexibility in treatment. The strap is adjustable for different hand sizes, and the cartridge is easy to replace without interrupting usage. This makes eBand the complete and practical solution for home-based smoking cessation.

A Smarter Future for Smoking Cessation

The eBand introduces a highly advanced way to quit smoking that focuses on the individual. By detecting withdrawal symptoms early and responding with accurate medication doses, it creates a balanced process that reduces stress without relying on constant willpower. Its technology supports real-time feedback, adaptive dosing, and seamless user experiences. Instead of forcing users to wait for a scheduled patch or chew gum on a fixed schedule, eBand gives support when it is actually needed. With every dose, the user moves closer to a nicotine-free life in a smarter, healthier way. The eBand represents the next step in personalized addiction therapy—quietly working on the wrist, but making a meaningful difference every day.
