The Harvested Energy for MEMS Monitoring Devices Explored
The 8th Livingston Nanotechnology Conference was held in New York last month with two keynote speakers: J. Wellinghoff, Chairman of FERC with a report on “Priorities in Energy Infrastructure” and K. Lightman, CEO of the MEMS Industry Group speaking on her industry’s trends.
Like the organizer of the conference, the ever enterprising and talented Mr. Scott Livingston, CurePatch’s team shares a common interest in the biggest industry drivers such as renewable harvested energy sources, security face control, MEMS (nano-heterostructure solar cells) and smart energy-saving algorithms.
As a matter of fact, Dr. Goldstein SEO of CurePatch explored these ideas some time ago in the report “Energy-on-Demand”: most of power consumption in the near future will trend towards energy-on-demand based on local hybrid systems.” For example, the amount of energy-on-demand needed to power a compact (1 sq. inch) medical device amounts to about 1mW (dissipation in-ear, 15,000-hours life) and 10mW (at surface-of-skin, 150-hour life) respectively (Industry sources). Estimates of power harvested from human body from vibration/motion are around 25µW; temperature difference 0.6mW; indoor and outdoor light 60µW and 60mW respectively. Just think of it: a MEMS accelerometer uses only 300 nanoA in motion-activated wake-up mode!
This is good news for designers of MEMS medical devices because the amount of energy-on-demand needed to run their devices is measured in milli watts and lest which could be harvested from the environment or from a human body”.
Currently the ultra-low-power (ULP) technology is utilized in electronics equipment by many companies such as Texas Instruments, HP, Bosh and STMicroelectronics, the latter growing almost twofold in 2012. According to Moore’s law, MEMS devices will steadily shed weight and size, lose appetite for energy and get cheaper.
CurePatch are platform integrators that are looking to design a single-board device to simplify the use of electronics in wireless monitoring. They declare a new era of autonomous, remote-monitoring wireless medical devices powered by efficient, renewable (hybrid) energy sources, equipped with a flexible multi-sensor platform the size and weight of the USA quarter coin (dime), with a set of solutions for the minimization of data volume transferred to lower power consumption and this is a real innovation.
First, the design of CurePatch products is ingeniously simple, using a multilayered modular patch in a flexible casing. Second, the device feeds from hybrid ULP sources of energy using flexible battery and/or light, thermoelectric, harvesting human-body parts’ vibrations (movement, sounds and breath). Third, and probably most important, it has managed to integrate the advanced ideas from different sciences to create an innovative concept.
While smart phones are becoming smarter and smaller, their success is attracting investors to standalone wearable devices which are popular in the health and fitness industry. It is estimated that the market for these devices will expand at a compound annual growth rate of almost 40% till 2017. Although these wearable sensoring devices are slimmer than smart phones they are sculpted in the image of traditional watches and gadgets. They look like a gadget and act like a gadget, being dependent on one energy source (a battery with a short life) and current hunger for any medical or sports gadget.
A CurePatch device with a buzz sensor similar to StickNFind which rose $0.5M (expecting a mere $70,000) is cheaper and may be disposable; such devices are attached to pets or people and help to find either humans or pets with a smart phone.
Small and easy to use, and equipped with a MEMS solution and harvesting environmental energy, it is beautiful solution.
