Smart sensor technology in healthcare & protection

  1. 1. PARTS PLAYED BY US:- DEEPIKA :: Handled the research Biosensors & various connecting services like (ZigBee/ IEEE standard 804.15.6, Bluetooth, WPAN, WLAN) and networks with the main station. OSHIN :: Handled the research on various applications and devices which work as Smart Sensors in healthcare and their future prospects and firmness in e-health fields.
  2. 2. OBJECTIVE To deal with various technologies which provide smart sensing in healthcare and compare them for their energy usage and battery life and discuss the format of communication to the database of these devices. To put forward devices which use smart sensors in advanced medical check-ups. To discuss the prospects of upcoming technology called Smart Dust in e-health and its advantages and effects for better deployment of trustworthy services in healthcare keeping in mind all the capabilities of the Smart Sensors.
  3. 3. SENSORS USED IN HOSPITALS What do they measure? •Temperature •Blood Pressure •Pulse •ECG (Heart Rate) •Respiratory Rate •Blood Sugar
  4. 4. APPLICATIONS OF E- HEALTH SENSORS • Patient Monitoring Blood pressure, blood sugar etc. • Environmental Tests Environmental Pollution • Diagnosis Patient Monitoring, Dope Testing, Cancer or Tumor analysis.
  5. 5. BIOSENSO RS • A biosensor is an analytical device, used for the detection of an analyte, that combines a biological component with a physiochemical detector. • The sensitive biological element(e.g. tissue, microorganisms, organelles, cell receptors, enzymes, antibodies, nucleic acids, etc.), a biologically derived material or biomimetic component that interacts (binds or recognizes) with the analyte under study. The sensor which can measure heart and brain activity (ECG, EEG and EMG).
  6. 6. BIOSENSORS-AN EXAMPLE • A common example of a commercial biosensor is the blood glucose biosensor, which uses the enzyme glucose oxidase to break blood glucose down. • In doing so it first oxidizes glucose and uses two electrons to reduce the FAD (a component of the enzyme) to FADH2. • This in turn is oxidized by the electrode (accepting two electrons from the electrode) in a number of steps. • The resulting current is a measure of the concentration of glucose. In this case, the electrode is the transducer and the enzyme is the biologically active component.
  7. 7. APPLICATIONS OF BIOSENSORS • Glucose monitoring in diabetes ← historical market driver. • Detection of pathogens. • Routine analytical measurement of folic acid, vitamin B12 etc as an alternative to microbiological assay. • Drug discovery & evaluation of new compound biological activity.
  8. 8. Smart sensor enhances the following applications:  Self calibration: Adjust deviation of o/p of sensor from desired value.  Communication: Broadcast information about its own status.  Computation: Allows one to obtain the average, variance and standard deviation for the set of measurements.  Multisensing: A single smart sensor can measure pressure, temperature, humidity, gas flow and infrared, chemical reaction surface acoustic vapour etc.  Cost effective: less hardware and reduction of repetitive testing make smart sensor cost effective.
  9. 9. 1. Mertia Sensing Device :- A small sensor is worn on the body and is attached using a skin-friendly adhesive. The low-profile design makes it suitable for daily activities like showering and exercise. The sensor is built to gather a variety of patient information, from heart rate and respiration to sleep duration and activity levels.
  10. 10. ZigBee is targeted at applications that require a low data rate, long battery life, and secure networking. ZigBee has a defined rate of 250 kbit/s, best suited for periodic or intermittent data or a single signal transmission from a sensor or input device ZigBee is a specification for a suite of high level communication protocols using small, low-power digital radios based on an IEEE 802 standard for personal area networks. ZigBee is seen as a key technology for home automation and sensor networks, but its characteristics can be extremely valuable in some healthcare applications as well. 2. ZigBee(IEEE 802.15.4)
  11. 11. 3. MEDIC • Acquire data from patients in real world • It sends data to the centralized server and the centralized server forwards data to all the nodes • It can be configured from the remote server • Wearable sensors to patients for comfortability
  12. 12. 4. Smart dust:- Smart dust is a theoretical concept of a tiny wireless sensor network, made up of microelectromechanical sensors (called MEMS), robots, or devices, usually referred to as motes, that have self-contained sensing, computation, communication and power. • Blood pressure sensor, Weight scale. • Emfi-sensors for exercise equipments/bed. • Low resolution IR camera. • Ultrasound radar. • Capacitive floor sensors. • ZigBee sensor network. • Connection to local and remote servers. • Strong collaborative, and robust clinical research with population studies is required!
