With this, lead researcher <\/span>Takeshi Kawano<\/span><\/a>, associate professor of electrical and electrical information engineering at the university, and his team hope to revolutionize how standard materials are used in stretchable electronics. <\/span><\/p>\n

The study is <\/span>published<\/span><\/a> in Advanced Healthcare Materials.<\/span><\/p>\n

What is a bioprobe?<\/b><\/h2>\n

A bioprobe is a device used to explore body parts or wounds. Currently, it is being used in both surgeries and medical studies. <\/span><\/p>\n

Elastomer is a standard material used to make stretchable devices, such as a bioprobe. However, because the material intrinsically requires a large strain-force to stretch it, an elastomer-based bioprobe cannot follow the deformation of sensitive organs, such as soft biological tissues. With the conventional bioprobe, researchers cannot study the natural deformation and growth of such organs. <\/span><\/p>\n

The Moment of Inspiration<\/b><\/h2>\n

One morning, Kawano woke up and saw his son playing with Origami and Kirigami. With just a few cuts, the boy made a plain old, flat paper into a highly stretchable material, deforming into multiple three-dimensional shapes. <\/span><\/p>\n

\u201cI saw him realize high stretchability of the paper <\/span>while creating the Kirigami designs,\u201d Kawano said in a statement. \u201cThis made me wonder whether it is possible to develop stretchable electronics using the concept of Kirigami.\u201d <\/span><\/p>\n

Advantages of a Kirigami-Based Bioprobe <\/b><\/h2>\n

Unlike the conventional elastomer-based bioprobe, which stretches the material itself, the newly developed Kirigami-based bioprobe stretches by bending each beam around the slits. As a result, a Kirigami-based bioprobe allows rigid and non-stretchable materials to be rendered more stretchable than elastomer-based bioprobe. <\/span><\/p>\n

Because of its high stretchability, a Kirigami-based bioprobe can be used to follow the shape of spherical and large deformable biological samples, such as a heart or brain tissues. <\/span><\/p>\n

\u201cThe stretchability of the Kirigami sheet can be determined by slit design,\u201d Kawano told The University Network (TUN). \u201cWe showed 1,100% stretchability. In addition, because the bending force of the thin film is smaller than the strain force of the elastomer materials, the strain-stress of the Kirigami structure is significantly smaller compared to the elastomer based stretchable devices.\u201d<\/span><\/p>\n

A Kirigami-based bioprobe\u2019s low strain-force also reduces the amount of force induced on organs and records biological signals in a less invasive way. <\/span><\/p>\n

\u201cWe are extremely excited that the fabricated Kirigami-based bioprobes possess the distinct advantages of high stretchability and deformability, and are capable of recording biological signals from the cortical surface and beating heart of a mouse,\u201d Kawano said in a<\/span> statement<\/span>. <\/span><\/p>\n

Applications for Kirigami-based Methods<\/b><\/h2>\n

The researchers believe that their Kirigami-based method can be used in any industry that requires devices, such as sensors or actuators, to be stretchable and have low strain-force. <\/span><\/p>\n

In particular, with Kirigami-based bioprobes, medical devices that are applied to sensitive organs will have higher accessibility and precision. For example, a Kirigami-based bioprobe\u2019s low strain-force will help researchers to study tissues and organs that exhibit time-dependent changes in their surface and volume because of possible growth or disease. When successful, findings can be instrumental in understanding mechanisms governing growth and diseases, such as Alzheimer\u2019s. <\/span><\/p>\n

\u201cThe small strain stress of our Kirigami bioprobe offers the device\u2019s small stress to the biological tissue, so the damage of the tissues can be minimized,\u201d Kawano told TUN.<\/span><\/p>\n

The team also believes that they can apply a Kirigami-based bioprobe to the brain-machine interface (BMI) technology and medical treatment for brain or heart diseases. <\/span><\/p>\n

\u201cBesides the stretchability, the Kirigami structure realizes the various three-dimensional transformation by using other slit designs,\u201d Kawano told TUN. \u201cTherefore, it has more capabilities to add functions to the film devices.\u201d <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
