Artificial knee and hip replacement surgeries are common today, with the majority of the implants using a plastic-on-metal joint interface. Unfortunately, plastic-on-metal joints are only temporary solutions, as most implants last 10-15 years before needing a second surgery to replace the worn device. This E-Team, incorporated as Magnetic Ventures, is looking to help joint replacements last longer with the Magnetically Assisted Artificial Joint, a patent-pending technology that lowers the contact stress at the joint interface through the use of magnets. The technology operates on a similar conceptual basis as MagLev trains, which utilize electromagnetic forces to lower friction between the train and track; as a MagLev track experiences a constant load from the train, the magnetic field needed to lift the train is constant. The team’s device uses an elastic material to control the distance between magnets in the joints and adjust the magnetic force; as the force in the joint increases, the magnets are pushed closer together, lowering the interface force and decreasing friction in the joint. The team has written a business plan, won several local business plan competitions, and developed and patented a prototype. With NCIIA funding they will test biocompatible elastic materials that would be used in their device, analyze various arrangements of magnets, and develop their network.
Biliary colic is a condition in which a gallstone becomes lodged at the gallbladder outlet, and, if left untreated, can cause severe and life-threatening infections. The most common treatment for this disease is surgical removal of the gallbladder, but due to a high risk of complications in the elderly and critically ill, surgery is not a viable option for over 200,000 patients per year. Instead, they're treated with conservative management, which is often unsuccessful. This E-Team is looking to develop a safe and effective alternative for these patients, as well as the large numbers of patients in developing countries where surgery isn’t an option. Since the gallbladder in patients with stones is actually normal and the stones are harmless provided they are kept away from the outlet, the team has developed a novel stainless steel filter device to prevent stones from reaching the outlet. The filter is delivered through a catheter and expands after deployment. Radial force holds the filter in place. The geometry of the filter prevents stones larger than two millimeters from passing.
Laser Doppler Vibrometers (LDVs) are sensors capable of detecting very small amounts of vibration from far away (100 meters or more). LDVs are used in bridge and building safety inspections, since structural defects give out small vibration signals, as well as in the automotive, aerospace, medical and industrial testing industries. The problem is that all current LDVs are manually operated, and it can take some time to find an appropriate reflective surface, focus the laser beam and get a vibration signal. This E-Team is developing a method to automate LDVs. The team's system, which involves hardware, software, and a web component, automatically selects a surface, tracks and focuses. The web component allows users to control the system remotely.
The team has filed a provisional patent and partnered with Polytec, an LDV company. With NCIIA funding they will build and test a working prototype, file for more patent protection, and look to pursue licensing with Polytec or other LDV manufacturers.
AYZH offers two products for resale by women entrepreneurs in developing markets:
Sheba Water Filter, a household water filter to provide high quality drinking water at a low cost
Clean Delivery Birth Kit: A hygiene kit for rural midwives to deliver babies for post natal health
Sheba is an innovative, low cost household water filter targeted specifically at women in rural Indian communities. It consists of a stacking system in which cloth bags filled with filter media (sand, gravel, ceramic, etc.) can be added and removed according to need. This design overcomes three problems with current water filters: slow rate of filtration, difficulty in cleaning filters, and difficulty in adapting filters to regional and seasonal variations in water.
Sheba was created in the International Developing Design Summit at MIT in 2007. Since then, the team has worked on prototyping the device. With NCIIA funding the team will further refine the design, test it in India, perform market research, re-design, and launch.

The Polytech Waterbag is a water filtration bag with disinfectant to be used in disaster relief situations. Developed and marketed by DayOne Response, the Waterbag will be sold to relief organizations and governments.
Providing people with clean drinking water is the one of the biggest challenges following a natural disaster. The most common solution is having aid agencies and governments deliver large five-gallon jugs of water, which is a costly and slow undertaking. Other solutions (hand-pumped filters, chlorine tablets) are either too expensive or only partially effective at treating contaminated water. This E-Team is developing a new way to ensure people have access to safe drinking water after a disaster: the Polytech Waterbag (PW). The PW is a ten-liter plastic bladder equipped with carrying straps and an integrated filter with a dispensing port. It’s designed to be used with Procter & Gamble’s PUR® chemical treatment packets; by using the packet along with the filter, complete water purification can be achieved. The PW comes with other features as well: a wide mouth for easy filling in shallow streams, a sediment trap to prevent recontamination, and more. The bags are 20x more compact than five-gallon water jugs to ship, and can treat enough water to supply a family of four for 5-10 days. The team has developed and patented a prototype, participated in and won several business plan competitions, and worked with Clinton Global Initiative project.
In 18 short months, NCIIA E-Team DayOne Response has moved from a student team with a cool idea to a company with a disaster-relief product being field tested by the US and Thai Marine Corps. Here's the story in pictures:
April 2010: incorporated as DayOne Response, and wins a contract with the US Navy to continue R&D on the waterbag via a joint technology exercise between the US and Thai Marines. The waterbag was one of the few technologies in that exercise to meet US military objectives for Humanitarian Aid and Disaster Relief missions.
While solar energy is an attractive option to provide the green energy of the future, it remains burdened by high installation costs and hasn’t been as widely adopted as it should be. Part of the problem is the physical process of installation: solar panels require mounting brackets, outside breakers and ground connections, and holes through walls for the wires. This E-Team is looking to reduce the cost of installing solar panels by developing a method to transmit solar energy wirelessly from outdoor solar panels to an indoor storage unit. The team is building on a novel wireless technology called WiTricity, which is capable of transmitting energy through walls without direct cable connections. With NCIIA funding the team will create a proof-of-concept prototype, research target markets and applications for the technology, and move toward commercialization by writing a business plan and securing IP.
Last week they won the second place award (and $2,500) at NCIIA's BMEidea biomedical engineering competition in New York. A couple of days later, the University of Cincinnati's SurgiSIL team picked up third place and another $5,000 at the ASME Innovation Showcase, held in Palm Desert, CA.
The winners were:
1st place ($10,000) - Rice University's PRIME team
2nd place ($7,000) - MIT's Solar ORC team
3rd place ($5,000) - University of Cincinnati's SurgiSIL team.
The 'Lab-on-a Stick' team from Stanford University has won this year's BMEidea (biomedical engineering) competition, taking away a cash prize of $10,000. Teams from the University of Cincinatti and Brown University were second and third. The winners were announced at today's Medical Design Excellence Awards ceremony in New York.
