The most important turning point in the history of sensors in healthcare was the advent of micro-system technologies for use in sensors for both, medical & pharmaceutical applications over the latter half of the previous decade. Micro-system technologies such as MEMS, CCD, and CMOS for miniature sensors and micro-fluidic chips have revolutionized the medical & pharmaceutical electronics segment by allowing smaller form factors, greater accuracy & precision characteristics, advanced control and low power consumption in devices & equipments. These technologies have enabled rapid deployment of sensors in several sophisticated medical & pharmaceutical equipments.
Some of the sensors and related devices that came into picture due to micro-system technologies over the past decade include pressure sensors for blood pressure, respiratory or kidney dialysis monitoring; accelerometers for pacemakers; silicon microphones, micro-actuators and microelectrodes for hearing aids; microelectrodes for cochlear implants; micro-pumps for infusion drug delivery; needle-free injection devices; IR ear thermometers; atomizers for nasal or pulmonary drug delivery; ultrasound sensors for medical imaging; neural stimulation for devices; smart pills for imaging; accelerometers for human fall detection; Micro-needles for trans-dermal drug delivery; active patches for trans-dermal drug delivery and so on.
Thus, it can be seen that owing to several revolutionizing factors and game changers, the sensors market in healthcare applications has evolved from an infant to a gigantic
