A smart Bandage technology
- 1. A Seminar Presentation on Smart Bandage Technology Under the Guidance of PUSHPALATHA .S Associate Professor Department of DECS VTU,PG Centre,Mysuru Presented by Gopinath k v 4VZ16LDS05
- 2. INTRODUCTION • Advances in wearable and flexible electronics along with the growth of wireless networking have created new paradigms of applications for smart living. • Increase in population and rising cost of healthcare services have also created a growing demand to monitor a patient‟s health in personal environment outside of a hospital. • Chronic wounds are wounds that do not follow normal healing processes and timelines. • They bleed randomly and show variations in pH levels as a result of infection. • External pressure can also cause these wounds to become chronic.
- 3. Why It Is Better ? • There are currently no commercially available wireless devices to continuously monitor the wound-healing process. • The proposed smart bandage, for the first time, provides a complete wearable system to wirelessly monitor chronic wounds in real- time.
- 4. Technology Details • This technology comprises two parts . 1) The first part contains a disposable bandage with inkjet-printed sensors. 2) second part consists of a reusable electronic sensors.
- 5. Technology Details(cont..) • (a) Bottom side of the bandage showing printed carbon based sensor electrode. • (b) Top side of the bandage showing folded connection of the bottom electrode. • (c) Top side of inkjet printed circuit board on kapton tape. • (d) Bottom side of the circuit board highlighting vias and pads for connecting bottom sensor electrode.
- 6. • (e) Detachable electronics comprising Kapton printed circuit tape after mounting of the components. • (f) Electronics being mounted on the bandage. • (g) Smart bandage enclosed by a bandage strip acting as a cover package. • (h) The detachable electronics can be easily removed from the bandage after use.
- 7. How It Works? • The smart bandage is part disposable and part reusable. The sensors used to detect bleeding, pH levels and external pressure on the wound are located on a disposable bandage • whereas the electronics on the flexible kapton tape can be detached and reused multiple times. • The capacitive sensor detects bleeding, as well as pressure levels on the wound. • A resistive sensor detects pH levels on the wound. The changes in capacitance and resistance are processed by the electronics, and the information is sent in a wireless fashion. • The wireless communication is done through an inkjet-printed loop antenna that is integrated with the circuit. This data can then be sent to remote health care providers using either the mobile network or the internet
- 8. Antenna measurement • The system level measurements have been performed that involve the wireless tests of the bandage with electronics mounted. • The active pattern is omnidirectional as expected from a loop antenna. Also the antenna is impedance matched at the operating frequency of 2.4 GHz.
- 9. Applications • Consumer healthcare • Hospitals and long-term remote health care • Bed sore management
- 10. Benefits • Reduces healthcare costs for patients. • Detects infections in a timely manner • Better wound management • Reusable electronics can be used on multiple disposable bandages • Pressure sensors can alert patients and help them avoid pressure ulcers • Provides dressing alerts for patients • Hassle free wireless and real-time monitoring
- 11. CONCLUSION • The development and characterisation of the sensors capable of providing qualitative and quantitative data. • The measurement of pH has been suggested as a useful marker for both wound infection but also for assessing healing physiology. • The development of new, rapid PoCT diagnostics is needed to allow the early detection of the non- preventable infection of wounds.
