Profile
The technology was conceived at the University of Wisconsin-Madison lab for advanced materials for energy and electronics under the direction of Professor Michael Arnold. The impact of nanomaterials on society has often been limited because it is difficult to synthesize, purity, process, organize, and integrate nanomaterials and nanostructures. Our research especially draws from multiple disciplines to address fundamental materials challenges - in controlling the growth, processing, ordering, and heterogeneity of nanomaterials and in understanding phenomena beyond the scale of single nanostructures - that must be overcome to exploit these exciting components in technology.

Remote Control of Soft Robots

Soft materials, such as rubber or polymers that can endure drastic changes to their shape, are promising for applications where flexibility and shapeshifting abilities are paramount. For example, these materials can be used to create soft robots suited for specialized tasks, ranging from medical devices that could navigate around inside the body to robots for search-and-rescue missions that can squeeze through small openings.

New Sensor Could Help Prevent Food Waste

As flowers bloom and fruits ripen, they emit a colorless, sweet-smelling gas called ethylene. Chemists have now created a tiny sensor that can detect this gas in concentrations as low as 15 parts per billion, which they believe could be useful in preventing food spoilage.

SysteMECH

SysteMECH have developed a direct die-placement technology to attach thin dies (unpackaged ICs) to flexible substrates. This promises to avoid the damage that can occur to bare dies using typical pick-and-place methods and increase yields.

Engineers Mix and Match Materials to Make New Stretchy Electronics

At the heart of any electronic device is a cold, hard computer chip, covered in a miniature city of transistors and other semiconducting elements. Because computer chips are rigid, the electronic devices that they power, such as our smartphones, laptops, watches, and televisions, are similarly inflexible. Now a process developed by engineers may be the key to manufacturing flexible electronics with multiple functionalities in a cost-effective way.

Machine learning you can dance to

Today's digital music producers face a common dilemma: how to mesh samples that may sound great on their own but do not necessarily fit into a song like they originally imagined. One solution is to find and audit dozens of different samples, a tedious process that can take time to finesse.

Flexible electronics and smart bandages are key to cost savings

Flexible electronics and smart bandages are key to cost savings in the future of advanced wound care. Advanced wounds, referring to those that are non-healing for more than 4 weeks, are on the rise around the world. This is because there are an increasing number of people with poor wound healing ability, including the rising number of elderly people over 65 years of age, and the rising number of people with Type 2 diabetes.

Fuel cell advance a breath of fresh air

A promising alternative to conventional power plants, solid oxide fuel cells use electrochemical methods that can generate power more efficiently than existing combustion-based generators. But fuel cells tend to degrade too quickly, eating up any efficiency gains through increased cost.

Light provides control for 3D printing with multiple materials

3D printing has revolutionized the fields of healthcare, biomedical engineering, manufacturing and art design. Successful applications have come despite the fact that most 3D printing techniques can only produce parts made of one material at a time. More complex applications could be developed if 3D printers could use different materials and create multi-material parts.
