Self-healing materials for robotics made from ‘jelly’ and salt

sc604 — Fri, 18 Feb 2022 16:54:17 +0000

̽��ֱ��low-cost jelly-like materials, developed by researchers at the ̽��ֱ�� of Cambridge, can sense strain, temperature and humidity. And unlike earlier self-healing robots, they can also partially repair themselves at room temperature.

̽��ֱ��results are reported in the journal NPG Asia Materials.

Soft sensing technologies could transform robotics, tactile interfaces and wearable devices, among other applications. However, most soft sensing technologies aren’t durable and consume high amounts of energy.

“Incorporating soft sensors into robotics allows us to get a lot more information from them, like how strain on our muscles allows our brains to get information about the state of our bodies,” said David Hardman from Cambridge’s Department of Engineering, the paper’s first author.

As part of the EU-funded SHERO project, Hardman and his colleagues have been working to develop soft sensing, self-healing materials for robotic hands and arms. These materials can detect when they are damaged, take the necessary steps to temporarily heal themselves and then resume work – all without the need for human interaction.

“We’ve been working with self-healing materials for several years, but now we’re looking into faster and cheaper ways to make self-healing robots,” said co-author Dr Thomas George-Thuruthel, also from the Department of Engineering.

Earlier versions of the self-healing robots needed to be heated in order to heal, but the Cambridge researchers are now developing materials that can heal at room temperature, which would make them more useful for real-world applications.

“We started with a stretchy, gelatine-based material which is cheap, biodegradable and biocompatible and carried out different tests on how to incorporate sensors into the material by adding in lots of conductive components,” said Hardman.

̽��ֱ��researchers found that printing sensors containing sodium chloride – salt – instead of carbon ink resulted in a material with the properties they were looking for. Since salt is soluble in the water-filled hydrogel, it provides a uniform channel for ionic conduction – the movement of ions.

When measuring the electrical resistance of the printed materials, the researchers found that changes in strain resulted in a highly linear response, which they could use to calculate the deformations of the material. Adding salt also enabled sensing of stretches of more than three times the sensor’s original length, so that the material can be incorporated into flexible and stretchable robotic devices.

̽��ֱ��self-healing materials are cheap and easy to make, either by 3D printing or casting. They are preferable to many existing alternatives since they show long-term strength and stability without drying out, and they are made entirely from widely available, food-safe, materials.

“It’s a really good sensor considering how cheap and easy it is to make,” said George-Thuruthel. “We could make a whole robot out of gelatine and print the sensors wherever we need them.”

̽��ֱ��self-healing hydrogels bond well with a range of different materials, meaning they can easily be incorporated with other types of robotics. For example, much of the research in the Bio-Inspired Robotics Laboratory, where the researchers are based, is focused on the development of artificial hands. Although this material is a proof-of-concept, if developed further, it could be incorporated into artificial skins and custom-made wearable and biodegradable sensors.

This work was supported by the Self-HEaling soft RObotics (SHERO) project, funded under the Future and Emerging Technologies (FET) programme of the European Commission.

̽��ֱ��Internet of Stings: research will probe privacy and legal concerns of smart devices

sc604 — Fri, 22 Oct 2021 08:43:11 +0000

These questions have been worrying researchers at the ̽��ֱ�� of Cambridge Department of Computer Science and Technology. Now they are launching a year-long investigation into the ways our information is being collected and whether or not these always comply with regulations and the law.

Working in collaboration with colleagues at Imperial College London, they will probe the data that flows from the Internet of Things – the networked consumer devices, such as smart printers, doorbells and toys, that are an increasing presence in our homes.

Backed by a grant from the Information Commissioner’s Office, the UK’s data protection regulator, they will be investigating what Dr Jat Singh describes as ‘the Internet of Stings’.

Research shows that information from our devices often finds its way to a range of third parties, such as user-tracking and advertising networks that may mine it for valuable information about consumer behaviour. He’s also worried about the occasions when data is transmitted from one country to another where there may be different rules, rights and restrictions around data and its use.

So Singh and the research team want to investigate the transmission of data from our devices to find out if it is in line with relevant law – and to inform consumers about the potential of what we can do to have better control over our information.

“We see ‘smart’ devices increasingly being worn on people's bodies and used in people's homes,” said Singh. “However, it’s often unclear what happens with the data these devices collect: where that data goes and how it is used. This is concerning, given these devices can often collect highly personal, private and sensitive information about ourselves and our lives.

“This project seeks to shed light on the state of current commercial data practices by analysing the nature of data flows from both a technical and a data rights, perspective. We aim to show if there are any data protection implications and concerns in the consumer smart device landscape so that we can empower policymakers, regulators, and individuals alike.”

Dr Singh leads the Compliant & Accountable Systems Research group, a team of researchers working at the intersection of technology and law. They consider ways in which technology could be better designed and deployed to meet legal and regulatory concerns and work to inform policymakers and regulators about the technical realities of new and emerging technologies.

Technical network-monitoring mechanisms have been used to establish the ways in which data is transmitted, the patterns of transmissions, and the destinations it ended up in. “This showed that potentially problematic data-flow appears to be rife in the Internet of Things,” said Singh.

Over the next year, they’ll be taking a detailed look at whether devices actually transmit data in accordance with the privacy policies and other legal obligations of the companies that sell them.

They will also explore the implications of mitigations that consumers might use, such as the implications of blocking particular data flows.

They want to establish the nature and scale of any problems and see if vendor companies are being honest and fully transparent with their consumers and compliant with data protection and other laws. They also want to better inform not only device owners but also regulators and policy-makers about the suspected issues, which may help inform future interventions.

“Problems with the data practices of the consumer smart devices have been suspected for some time, but not fully examined – from both a technical and legal perspective,” said Singh. “We need to do so if we want a better, fairer and more compliant Internet of Things.”
