It is interesting to note that the choice of network technology could affect, to varying degrees, the utilisation of other computer system components and in particular processor (CPU).
It covers architectures and their components: processors, memory, and networks, and also looks at methodologies for multiprocessor design.
The bendable base layers make devices twist and stretch when attached to the skin, but they are limited by a lack of key components such as batteries and processors that currently do not exist in flexible form.
Zhenan Bao, a chemical engineer developing similar wearable health sensors at Stanford University in California, says that some key components such as batteries and processors do not yet have a flexible form suitable for skin patches.
According to the latest teardown report compiled by iSuppli, a market research firm in El Segundo, Calif., the bulk of what Apple pays for the iPhone 4's parts goes to its chip suppliers, like Samsung and Broadcom, which supply crucial components, like processors and the device's flash-memory chip.
Its annual supplier report lists 69 manufacturing facilities in the US, with US-based companies supplying components such as the glass in all iOS devices; iOS and Mac chips and processors; RF components for iPhone; and various display materials for iPhone, iPad and MacBook.
The company said a decline in the costs of components, like processors and memory, bolstered income.
The aim is achieved through a functional decomposition of the system, followed by an appropriate allocation of tasks to the different components of the system (ASICs and processors).
Certainly there have been quantitative improvements in a few individual components, notably displays, wireless bandwidth, and processors, but beyond that our computers, phones, tablets, hi-fis, headsets, routers, coffee makers, refrigerators, webcams, and so on have remained largely the same.
Self-sensing of hardware status is achieved by adding extra introspection sensors and corresponding drivers and is able to detect changes in hardware components such as sensors, actuators and processors, as well as unexpected hardware failures.
