<text>  Battery life is consistently listed as a major flaw of smartphones, smartwatches and other wearables. But this problem could soon be solved thanks to technology that promises to extend battery life for decades. Atmel has released its latest microcontrollers MCUs for a variety of gadgets that are so low power they can even harvest energy from a persons body. Atmel has released its latest microcontrollers MCUs for a variety of gadgets that are so low power they can even harvest energy from a persons body. Atmel said its MCUs extend battery life from years to decades, reducing the number of times batteries need to be changed in devices The ultra-low power SAM L microcontrollers are part of Atmels 32-bit ARM-based MCU range. These are all powered by chip maker ARMs Cortex M0 32-bit processors. A number of Apple devices, including the iPhone 5S and iPad Air are powered by chips based around ARM technology. During a demonstration of the microcontrollers to ARMDevices.net at this years CES, Andreas Eieland, Atmels director of product marketing demonstrated how he could power a radio by placing his hand on a panel. This panel recognised a change in temperature between the hand and the room and this was harvested to create charge. Mr Eieland said this is based on piezoelectric materials. The material is able to produce an electric charge when it stretches and is subjected to mechanical stress. PFC is a type of piezoelectric material made up of integrated electrodes, and an adhesive polymer matrix. The material is able to produce an electric charge when it stretches and is subjected to mechanical stress. Atmel said its MCUs extend battery life from years to decades, reducing the number of times batteries need to be changed in devices such as fire alarms, healthcare, medical, wearable, and devices placed in rural, agriculture, offshore and other remote areas. They use a third of the power of rival chips and tests have shown they are the lowest power microprocessor ever made. The microcontrollers run on the firms picoPower technology and Atmels Event System that makes different parts of the device work together to carry out tasks. By effectively sharing energy, the whole device uses less power and, subsequently, less battery. It can also manage how much energy is being used by other components to make them as efficient as possible. Plus, the technology is so low power it can harvest energy from the body using changes in temperature.

As Ars Technicas Sean Gallagher explained, the processor isnt powerful enough to run a computer desktop, for example, but does come with enough power and memory to stream media from a USB stick, send alerts from smart alarms and lights and run multiple apps. The firm said that the microcontroller itself can run for years on a single charge, but the battery life of the devices it is added to will depend on how much they are used. Atmels current model is designed for smart household devices and other gadgets that use relatively low power, but the technology has the potential to one day run on more power-hungry gadgets such as phones and tablets.
