　　The medical and fitness device market is currentlyundergoing a time of revolutionary change. Many traditionalmedical devices have evolved into home health and fitnessdevices. Devices that were primarily used in hospitals arenow available for in-home use, worn on the body and evenimplanted in the body. The demographics of those whopurchase medical devices have also changed. Previously,medical device manufacturers only needed to focus theirmarketing efforts towards committees of doctors andadministrators who made the purchasing decisions. In today’senvironment, they now must also market their products toconsumers who require medical and fitness devices that are:

　　■ Portable or wearable

　　■ Lower cost

　　■ Have more powerful feature sets

　　■ Easier to use

　　■ Have a longer battery life

　　■ Reliable and can connect in several ways to smartphones and tablets

　　Since consumers are constantly upgrading their smartphones and tablets, manufacturers of medical devices will need todecrease their design cycle and develop new products to keep up with the latest trends in consumer electronic devices.

　　This rapid evolution in medical and fitness device technology may seem overwhelming, but it can also be embraced as anexciting design challenge. Where can you turn to help you meet this challenge? Microchip offers you powerful technologysolutions and outstanding support as you create new product designs for the medical and fitness markets.

　　Patient monitors measure, record, distribute and display combinations of biometric values such as heart rate, SPO2,blood pressure, temperature and more. High-capability, multi-function monitors are typically used in hospitals and clinicsto ensure a high level of quality patient care. Portable patient monitors are designed to be compact and power-efficient.

　　This allows them to be used in remote areas or by paramedics to aid diagnosis in the field and to enable monitoring andtransmitting data to health care providers in other locations.

　　To meet the demands faced by designers of patient monitors, Microchip offers a broad portfolio of highly integrated MCUs,graphics technology, software libraries, and connectivity solutions. This broad offering also enables innovation in the designof stand-alone biometric devices such as blood pressure monitors, pulse oximeters and ECG/EKG. We deliver solutions forlow-noise analog signal conditioning, touch sensing technology, LCD control, wired and wireless connectivity, motor controland high-speed memory to support patient monitoring functions.

　　Microchip has what patient monitor designers need:

　　■ Powerful, highly-integrated 32-bit PIC MCUs with flexible integrated graphics, USB,and 10/100 Ethernet enable the design of every kind of patient monitor for use inhospitals, doctors’offices or in the field.

　　■ A broad range of 8-, 16-, and 32-bit PIC MCUs and other solutions enable thedesign of blood pressure monitors, pulse oximeters, ECG and other sub-sections ofa patient monitor design.

　　■ Signal conditioning components such as low-offset/low-noise op amps andhigh-resolution ADCs for accurate and reliable signal capture and conversionfrom sensors.

　　■ Agency-certified Wi-Fi, Bluetooth, Bluetooth Smart, and ZigBee solutions for fastintegration with existing networks.
