What are smart tattoos that monitor your health?

Smart tattoos represent a groundbreaking convergence of traditional tattoo artistry and advanced technology. In this exploration, we delve into the importance of digital tattoos, the underlying innovative tattoo technology, and the myriad benefits they bring beyond aesthetic expression. From health monitoring to interactive experiences, smart tattoos pave the way for a new era of personalized, tech-infused body art.

Purpose of Smart Tattoos

Smart tattoos can perform specific functions, like health monitoring and device interaction.

  • Monitoring health

Smart tattoos can track health metrics like heart rate, blood pressure, glucose, and hydration. People can use this data to make informed decisions.

  • Interacting with devices

Smart tattoos can control smartphones, computers, and smart home devices. You can also use voice commands or gestures, such as swiping and tapping.

  • Personalizing experiences

A brilliant tattoo can unlock doors, log into computers, and access personalized information.

Smart tattoos represent a fusion of traditional body art and cutting-edge technology, serving various purposes beyond aesthetics. Unlike conventional tattoos, the smart tattoo can perform functions such as monitoring health, providing interactive experiences, or providing a personal identifier.

The technology of Smart Tattoos

  • Biometric Monitoring

In addition to sensors that monitor physiological data, bright tattoos can monitor glucose levels and heart rates. External devices can receive this information in real-time and track the patient’s health.

  • Interactive and Display Features

Some smart tattoos incorporate LED lights or electronic ink to create dynamic visual displays. These can change in response to external stimuli or be programmed to convey specific information.

  • NFC (Near Field Communication)

NFC-enabled smart tattoos can store and transmit data. With a tap of the tattoo against a suitable device, you can share contact information or access secure locations.

  • Conductive Inks

Conductive inks create circuits directly on the skin, allowing for flexible and customizable designs. These circuits can be connected to external devices, enabling diverse functionalities.

  • Sensors

Bright tattoos use a variety of sensors to collect data about the wearer’s body. These sensors can track various health metrics, such as heart rate, blood pressure, glucose levels, and hydration levels. Some smart tattoos also include sensors that measure environmental factors like temperature and humidity.

  • Circuits

Smart tattoos contain minuscule circuits that process sensor data. Smart tattoos may include microprocessors that enable them to store data, communicate, and perform complex tasks.

Future Applications of Smart Tattoos


  • Health Monitoring

Smart tattoos could revolutionize healthcare by providing continuous, non-invasive monitoring of vital signs. Patients with chronic conditions could derive considerable benefits from this.

  • Augmented Reality

Integrating smart tattoos with augmented reality technology could enhance interactive experiences. Users can control digital interfaces by interacting with their smart tattoos.

  • Security and Authentication

Smart tattoos with unique identifiers could be used for secure access control, replacing traditional methods like keycards or passwords.

  • Personal Expression

Smart tattoos could become a new form of self-expression as technology advances, allowing individuals to showcase dynamic, programmable designs that reflect their moods or interests.

Examples of Smart Tattoos

  • Chaotic Moon’s Tech Tats

Chaotic Moon has developed temporary smart tattoos called Tech Tats. They use conductive paint to create circuitry on the skin, enabling various applications, including health monitoring and payment processing.

  • MIT’s Dermal Abyss

Dermal Abyss explores the use of biosensors in tattoos to monitor health. It replaces traditional tattoo inks with biosensor inks that change color in response to variations in interstitial fluid.

  • Motorola’s Digital Tattoo

Motorola has patented a smart tattoo that can authenticate a user’s identity. Unlocking devices and accessing secure information with an NFC-based tattoo, eliminating the need for passwords is possible.

  • Glucose-monitoring tattoos

Digital tattoos come in two varieties: transient and permanent. Some of Chaotic Moon’s Tech Tats, like the ones you can remove quickly, are intended to last a long time.

  • Heart-rate tracking tattoos

These can be used to track heart rate in people with heart disease or other conditions affecting the heart. As a result, they can monitor their health and make informed decisions about how much exercise and activity they should engage in.

  • Skin temperature tattoos

These tattoos can track skin temperature in people with skin conditions such as eczema or psoriasis. This can help them monitor their condition and identify triggers.

  • UV-exposure tattoos

These tattoos can be used to track UV exposure in people who are at risk of skin cancer. This can help them take steps to protect their skin from the sun.


Smart tattoos represent an exciting intersection of technology and body art, holding immense potential for various practical applications. As technology advances, the future of smart tattoos promises innovative ways to enhance healthcare, personal expression, and digital interactions.
