Market Opportunities for MEMS Energy Harvesting Devices – Bharatbook.com

MEMS Energy Harvesting Devices Technologies and Markets Report ( http://www.bharatbook.com/Market-Research-Reports/MEMS-Energy-Harvesting-Devices-Technologies-and-Markets.html ) gives Market driver analysis for challenges that go beyond energy density!

OBJECTIVES OF THE REPORT

This report focuses on MEMS energy harvesting devices from both technology and market points of view.

Special attention has been given to the market drivers for adopting MEMS energy harvesting devices in different market segments, factoring the progress of competing technologies and cost constraints.

It appears that the numerous opportunities for energy harvesting devices must be analyzed carefully, taking into account all aspects of the final application from power consumption profiles to lifetime and size constraints. Applications screened cover automotive, medical, industrial machine monitoring and process control, home automation and defense.

The main developments in MEMS energy harvesting devices are described and compared to fuel cells and micro-batteries. The report also describes the challenges facing the current players and the current market trends and business models.

MAIN CHALLENGES

Within an environmentally conscious world, MEMS Energy harvesting devices promise in principle a cleaner and almost perpetual solution to powering small systems avoiding the use and waste of polluting batteries.

Ever optimistic market projections are predicting billions of dollars in revenue for ubiquitous sensor networks in the next five to ten years and derive from these numbers large energy harvesting sales and volumes.

And indeed, MEMS energy harvesting devices have been a hot topic in MEMS R&D for some years with spectacular developments driven by DARPA programs within the Hi-MEMS cyborg insects.

The reality is that beyond the technological buzz, commercial applications are slowly starting to get to market for industrial applications and home automation appliances. This is driving the first volumes for energy harvesting applications, but not necessarily at the micro scale. Hot market segments in 2007 and 2008 such as tire pressure monitoring systems where batteries are currently the dominant solution have driven enormous efforts but the market dynamics have not made it possible to accept a premium price for alternative solutions.

We have focused our efforts in this report into a fine analysis of the market drivers for using MEMS energy harvesting devices, in comparison to micro batteries, micro fuel cells, or even solar cells. Different application fields from medical to home automation, industrial process control, machine monitoring or transportations have been analyzed in this report.

The challenges facing this technology were examined in a broad view, from a technology but also from a whole product point of view. There are needs for better power density but also for less power consuming electronics and wireless communications!

MARKET METRICS

Market acceptance of MEMS energy harvesting devices is a function of several parameters that are studied in the report.

These parameters include, but are not limited to: size, cost, amount of power generated versus amount of power needed by the system and projected lifetime for the energy harvesting device compared to the system parts lifetime.

A major factor to be taken into account is whether there is enough power harvested for a particular application from a particular environment, and whether the scavenged power needs to be stored. As piezoelectric MEMS energy harvesting devices can currently power sensor nodes requiring 60 uW according to the latest developments, a companion energy storage device would be necessary for most applications.

Commercial success will come from a full understanding of all aspects of the system to be powered and of the data receiver nodes.

Challenges include ultra low power electronics and wireless data transmissions rates and standards.

2009 Mems Inertial Sensors Status And Trends Of 2010

Inertial sensors including accelerometers (or accelerometer sensor of dollars) and the angular rate sensor (gyroscope) and their single, double, three-axis combined IMU (Inertial Measurement Unit), AHRS (including magnetic sensor attitude reference system).

Is the use of MEMS accelerometer inertial sensing the quality of force measurement sensor, the general standard of quality from the block (sensor element) and the detection circuit. According to the different sensing principle, mainly piezoresistive, capacitive, piezoelectric type, the tunnel current-type, resonance type, thermal and electromagnetic coupling type and so on.

In 1998, the United States CSDL design and development of the first MEMS gyroscope. In the same year, Drapor lab developed another form of MEMS gyroscope.

MEMS gyroscope is the use of vibration-mass has been the base (shell) driven rotation of the Coriolis effect to the principle of the angular velocity sensor is made.

Mainly in the form of framework-driven (inside and outside the framework of the two kinds) comb-drive type, electromagnetic-driven and so on.

IMU because it is combination of MEMS technology, micro-inertial measurement unit, so many places called MIMU. Mainly by the three MEMS accelerometers and three gyro and the solver circuit.

AHRS consists of three magnetic sensors, compared with the IMU, and based on four elements in France to understand calculation, can output directly to a sports body pitch angle, roll angle and heading angle.

Low-precision MEMS inertial sensors, as consumer electronics products are mainly used in mobile phones, game consoles, music players, wireless mouse, digital cameras, PD, hard disk protector, smart toys, pedometer, anti-theft system, GPS navigation, portable. Because of acceleration measurement, tilt measurement, vibration measurement and even rotational measurements and other basic measurements, to be excavated consumer electronics applications will continue to emerge.

Intermediate grade MEMS inertial sensors for industrial and automotive grade products, are mainly used in automotive electronic stability systems (ESP or ESC) GPS-assisted navigation systems, automobile airbags, vehicle attitude measurement, precision agriculture, industrial automation, large-scale medical equipment, robotics , instruments | instruments and meters, construction machinery and so on.

High-precision MEMS inertial sensors as a military-grade and aerospace level products, the main demand high precision, the whole temperature range, shock and other indices. Mainly used in wireless communications satellite, missile seeker, optical targeting systems, stability of the applications; aircraft / missile flight control, attitude control, yaw damping control applications, as well as medium-range missile guidance, inertial-guided GPS navigation applications, remote aircraft ship equipment, battlefield robots.

For consumer electronics of MEMS inertial sensors, the main requirement is that the low price, small size, narrow temperature range, so accuracy is low, or even functional products. Acceleration sensors, light weight, power consumption is small, generally measuring range 1 ~ 10g ~ 50g, Resolution 2mg ~ 10mg, top general in the range ± 300 ° / s, zero-bias in the 500 ° / h ~ 1000 ° / h, so some companies products do not give a zero bias indicators or to give 0.1 ° / s ~ 0.5 ° / s.

MEMS accelerometer can be produced at present the companies are more, most of the semiconductor, such as the United States, ADI, Invensense, ST, Freescale, Sensor Dynamics, MSI (ICSensor), MEMSIC (producer in Wuxi, China) Europe, VTI, Infine, production MEMS gyroscope’s the United States, ADI, Knoix, ST, Europe, Infine, Methes, Japan, Murata, National, Oki, Fujitsu. December 3 Di Semiconductor Co., Ltd. Shenzhen, Shanghai, China issued a consumer-grade MEMS gyro, a company in Wuxi is also in development.
