Perpetuum Vibration Energy Harvesting for wireless condition monitoring


Wireless Sensor Node Assessment Kit (wSNAK): Perpetuum’s deployable demonstration system is designed to confirm to original equipment manufacturers (OEMs) and end users the advantages of vibration energy harvesting for wireless condition monitoring with a quick, easy and low cost installation, the company says.

London – Wireless power is emerging as a popular concept since the profusion of personal and portable electronic devices has created a need for a convenient means to power these gadgets, eliminating the inconvenience and mess of several chargers and wires, says Frost & Sullivan . Industries too echo this sentiment, as wires augment cost and maintenance and limit technology application as a result. Scientists are considering several technologies for such applications and options are emerging.
Industrial applications include wireless condition monitoring, asset management, plant safety systems, and wireless instrumentation.
Control Engineering resources provide more on power harvesting and wireless power sources.
- Power: Digital converter growth; fuses, harvesting, supplies, transformers, UPS ;
- Wireless power: Vibration generator runs remote devices for free ; and
- Wireless in machines: Energy harvesting technology gets real .
New analysis from Frost & Sullivan , Wireless Power Supplies and Contactless Energy Transfer, finds that induction based wireless power could represent the next wave in powering portable electronics. It could also enable new applications in other sectors such as healthcare for powering implants to increase patient convenience and quality of life.
Wireless power has tremendous potential in various industries including consumer electronics, automotive, and process control. The power and energy industry is investing substantially in research on large-scale wireless energy transfer, as space-based solar power systems are attracting attention as an alternative form of energy to meet energy demands in the long term. If adopted, this technology will facilitate the use of all electrical devices, which is a highly sought-after purchase factor when choosing cell phones or laptops.
“Moreover, natural deposits such as coal and petroleum are rapidly depleting, and one day, alternative energy sources will be needed,” say Frost technical insights research analysts Sharmishta S. and Agata Jozwicka. “If Earth-based natural energy sources will not satisfy the world's energy needs, space solar power systems could become the only alternative.”
As the home automation trend is catching on, several companies have developed wireless power technologies such as charging pads for use in homes and offices to power personal electronic devices.
Meanwhile, universities are researching ways to improve efficiency over longer ranges. Wireless power transfer is highly efficient at short distances; however, there tends to be substantial power losses when the transfer distance increases. In the case of power-hungry devices such as industry machines or even laptops, the transfer should be efficient enough to enable rapid recharging and should not interfere with the continuous working of the device during the recharge. Even wired chargers are not considered completely reliable since they heat up while charging, dissipating energy through heat.
To quell consumer apprehensions and increase customer acceptance of the technology, Frost says, scientists are studying techniques such as resonant induction, microwaves, and lasers although currently, these methods limit the amount of power that can be transmitted.
“The other problem here is that some of such devices are often large and so, there have to be trade-offs among the size of the devices, the proximity between the transmitter and receiver, and the amount of power to be used to recharge the device,” notes Jozwicka. “There is a need for complementary electronics capable of working at higher frequencies to improve the efficiency of the wireless power transfer.”
Even if all these performance requirements are met, potential users will still be wary about the safety of wireless energy transfer.
“This challenge is especially pertinent for personal and household devices, where the users are concerned about the impact of electromagnetic field, microwaves, or even radio waves on their health,” observes Sharmishta. “To accelerate the adoption of this disruptive technology in a conservative end-user market, it must be ensured that energy transfer technologies operate within regulation norms.”
Technology developers can increase use of wireless power in the consumer electronics segment through collaborations and agreements with original equipment manufacturers (OEMs) in incorporating a unified charging scheme across a range of products. To assuage fears of end users and expand the user base in the future, industry participants could also consider energy transfer with space solar power systems and lobby for international cooperation between governments, Frost advises.

Annual Salary Survey

Participate in the 2013 Salary Survey

In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.

Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
