Illness-Detecting Mask


  • Recently, The Illness-detecting mask with sensor have developed by BITS-Pilani Hyderabad.

Key highlights:

About: Face Mask

  • That a face mask can protect against COVID-19 and other respiratory diseases is well established.
  • Now, it can also be used as a non-invasive device to check one’s health as has been successfully demonstrated by researchers at the Micro-Electro-Mechanical Systems (MEMS), Microfluids and Nanoelectronics (MMNE) Lab on at the BITS-Pilani Hyderabad campus.
  • A Kirigami-based stretchable, flexible Laser induced Graphene (LIG) a 3-D carbon nanomaterial, for real-time attachments with surgical masks.
  • LIG is a widely used material for monitoring vital physiological signs such as breath rate (BR) or respiratory rate (RR), body temperature, pulse rate, and blood oxygen saturation.
  • Monitoring breath rate is considered as a parameter to detect diseases like cardiac arrest, asthma, pneumonia, pulmonary edema, and of course, COVID-19.
  • Researchers used the sensor attached to a gas mask to analyse the breath pattern of the subject seated on a chair by validating the change in resistance during inhalation and exhalation.
  • The rate of breathing generally varies based on age until and unless the person is diseased. Fitness of a person can be determined by Breath Index or simply, by measuring RR and DR.
  • The product is customisable and can be used to develop various sizes and patterns of ‘Kirigami’ (Japanese art of paper cutting giving a 3D element) based structures for patients across age groups and demographics. The sensor can be placed over the mouth and nose without causing any irritation while ensuring stable working.

Application of Mask:

    • Healthcare
    • Disease diagnosis
    • E-skin
  • The sensor has potential in wearable/flexible healthcare technology owing to its high sensitivity, flexibility, and cost-effectiveness.
  • And, it could help in the early detection of illnesses like heart disease, bronchitis, asthma, pneumonia, chronic obstructive pulmonary disease (COPD), sleep apnea syndrome (SAS), and lung cancer, thereby saving many lives, he explained.
  • The sensor could be used in a wide range of settings, such as fabric masks, surgical masks, oxygen masks, etc., making it suitable for evaluating symptoms of COVID-19 and other respiratory ailments.
  • The project was carried out under the aegis of Department of Science & Technology- Biomedical Device and Technology Development (BDTD) and has been accepted for publication in ‘IEEE Sensors Journal’.
