At also same home, a home setting can contribute to faster recovery. For example, if the patient recovering at home from heart surgery is wearing the smart shirt, the ECG can be transmitted wirelessly through mobile phone, internet etc to the hospital on a regular basis. This monitoring will help the patient feel more secure and will facilitate the recuperation while simultaneously.
WearableBioSensors reducing the cost time associated with recovery. Moreover, in the event of an emergency, the doctor can be notified instantaneously. Using the online medical records available over the web the physician can administrate the right investment at the right time at the right cost and indeed save a life, thereby realizing the full potential of the smart shirt technology.
Further more, persons who have known disorders can wear the smart shirt and be under constant monitoring of the physical conditions by medical personnel. The smart shirt technology has the means to provide unobstructed monitoring for individuals and can thereby play a critical role disease management for the large numbers of individuals at risk for high blood pressure, heart disease, diabetes, chronic bronchitis, and depression by enabling early systematic intervention.
The BITS-Life Guard computing architecture specification is centered around two computing cores a wearable computer and a vehicular computer. The wearable computer aims to take care of the physiological signal acquisition, their processing and communication to the vehicular computer. Whereas the vehicular computer would utilize its resources to take care of intensive computational tasks by collecting inputs from a heterogeneous set of sensing and.
WearableBioSensors communicating devices. Figure 1 a and 1 b shows the hardware and software resource requirements of the overall computing architecture. These specifications help in listing the resource requirements for different units of the BITSLifeGuard wearable computing architecture discussed in this section.
Hardware Requirements Proper selection of all hardware resources play a crucial role as inappropriate resources may lead to an increase in the weight, cost, size and development time in such systems. Optimization of resource-utilization would eliminate all such burdens and result in a simplified and user friendly solution. In devising architecture for a particular wearable computing device following four important hardware components play an important role: Selection of processor is influenced by the scope of the application.
Initial wearable prototypes used multimedia audio and image processing using a generalpurpose CPU alone. With the availability of heterogeneous multicore system-on-chip SoC and partitioning the system specific task and DSP task, it has become possible to minimize cost and power consumption, achieve higher performance rate while the complexity increased for the embedded software developer to manage additional processor with respect to its programming and debugging .
The choice of processor is primarily governed by its energy conservation characteristics and the on-chip peripheral support that may include wireless radio transceivers, serial communication channels etc.
Majority of the power consumed in a typical handheld or PDA device has been found by the units like its processing core, during memory access, active speakers, back-light and front-light . Cores that use dynamic voltage scaling save power using software in its idle, sleep or active mode are preferred nowadays in portable system design .
These typical systems may consume. WearableBioSensors power from mW to mW on an average battery power of 3. Voluminous data collected over a period needs to be transferred to a back-end processing system without burdening the processor saves processors power consumption , thereby peripherals role like that of a DMA becomes crucial at this juncture.
Since the processing of acquired signals done on the fly, situations like a alarming the driver itself b inform persons who may be forming a personal area network due to being inside or around the vehicle, and c in case the driver does not respond to the alarm, sending an SOS signal to the vehicular computer to take further action. This requires that the short-range radio selected for this purpose must have good coverage area, no line-of-sight problem as well as a good amount of security implemented in the protocol stack of the channel itself thereby reliving the processing core from intensive computation as needed in the case of encryption and decryption algorithms.
The data transfer rate of the wireless channel influences the design in a way that the physiological data which require further processing at the back-end vehicular computer must be relayed at regular intervals due to less on-chip memory availability.
As communication radios consume more power during transmission and reception their exact power requirements must be met in accordance with the required design.
Unobtrusiveness is the key; i. Care must be taken in selection of electrodes which are disposable, require frequent gelling, and may produce some kind of skin ailments or health hazards. Appropriate sensors specific to a particular application must be selected by considering its electrical characteristics such as power consumption, sampling frequency and mechanical characteristics such as size, robustness as well as some environmental. WearableBioSensors issues like extreme weather conditions and its ability to operate for long hours.
The reliability and operability of sensors in wearable conditions not only influence the design but also facilitates the acceptability of these sensors in such a situation. Overall system design may also be governed by issues like choice of appropriate sensor type, sensor dimensions, location of sensors, power source, wireless scommunication range, mounting mechanisms, configuration and body safety due to wearable sensors.
Besides the above key requirements the supporting device selection becomes crucial if one had to build a body network of wired sensors. This may also include the analog signal conditioning circuits to convert the sensor data into a digitized form.
Wired connection of sensor nodes require that the communication to the processing unit be properly timed such that critical health related events should not be lost. Proper selections of baud rate, serial bus technology to be used, wireless channel communication rate etc.
This selection is also influenced by the on-chip peripheral support of the processing core. Software Requirements The real challenge lies in such system to have an operating system to meet the real-time requirements of the larger system.
Managing all resources and their timing is critical as large latency in responding to a specific task especially in an emergency would lead to loss of a life. A better solution could be to use a hard real-time operating system with small foot-print, less memory requirements, low latency, and with kernel reconfigurability support.
A choice. WearableBioSensors has to be made based upon the development support with a specific OS like what processor architecture does it support, features of the development tools Integrated Development Environment , what kind of API support available and other above mentioned requirements such that development would be less cumbersome and robust.
Functional Requirements Since the target application aims to assist drivers by knowing their health status, physical and mental fitness, fatigue level and other related parameters, it is required that the devices including the sensors may not let the driver in an awkward situation as well as distractions of any kind due to their placement, weight, size, overheating when the device is active must be avoided.
The wiring connections in case of body network of wired sensors must not obstruct the drivers normal driving. These issues can be tackled using proper design considerations. The functional requirements are influenced by the drivers age, his behavioral habits during driving etc. Thus, the rich vital signs delta steam from the smart shirt can be used to design and experiment real-time feedback mechanism as part of the smart shirt system to embrace the quality of care for this individual by providing appropriate and timely medical inspections.
Certain individuals are susceptible to anaphylaxis reaction an allergic reaction when stung by a bee adrenaline. By applying advancement in MEMS Micro-Electromechanical Systems technology, a feedback system including a dry delivery system-can be integrated into mechanism to guard against inadvertent control system. Likewise, the Smart shirts delta acquisition capabilities can be used to detect the condition when an individual is lapsing into a diabetic shock and this integrated feedback mechanism can provide the appropriate response to prevent a fatality.
Thus, the smart shirt represents yet another significant milestone in the endeavor to save and enhance the quality of human life through the use of advanced technologies. The ring sensor and smart shirt are an effective and comfortable, and mobile information infrastructure that can be made to the individuals.
Just as special-purpose chips and processors can be plugged into a computer motherboard to obtain the required information processing capability, the smart shirt is an information infrastructure into which the wearer can plug in the desired sensors and devices, thereby creating a system for monitoring vital signs in an efficient and cost effective manner with the universal interface of clothing. Advanced technologies such as the smart shirt have at partial to dramatically alter its landscape of healthcare delivery and at practice of medicine as we know them today.
By enhancing the quality of life, minimizing medical errors, and reducing healthcare costs, the patientcontrol wearable information infrastructure can play a vital role in realizing the future healthcare system. Just as the spreadsheet pioneered the field of information processing that brought computing to the masses.
It is anticipated that the smart shirt will bring personalized and affordable healthcare monitoring to the population at large, thus leading to the realization of Affordable Healthcare, Any place, Anytime, Anyone. WearableBioSensors Handbook of biomedical instrumentation ,Khandpur ,pp,, 4.
