Developable Rotationally Symmetric Kirigami‐Based Structures as Sensor Platforms

“…[16][17][18][19][20][21] However, the sensing is based on stretching of the fibers, typically unidirectional and poorly suited for integration with substantially rigid electronic components that do not tolerate well to repeated mechanical deformation. [28][29][30][31] While technologies to generate patterns and functional coatings in two dimensions are now highly evolved, the structures examined here are easily generated at the application-appropriate length scales using a laser or die cutter. Instead, an approach is needed where the device is flexible and curved, conforming to the body surface in use, yet is also flat and nonstretchable during fabrication to be compatible with dominant, scalable manufacturing and integration processes for electronics.…”

“…[22][23][24][25] The addition of cutting allows for greater control over the geometric design and system behavior.

Efficient Skin Temperature Sensor and Stable Gel‐Less Sticky ECG Sensor for a Wearable Flexible Healthcare Patch

“…In fact, many studies have examined flexible and stretchable sensors to monitor health data [1][2][3][4][5][6][7][8] such as skin temperature, [9][10][11] electrocardiogram (ECG), [12][13][14][15][16][17] chemical contents in the body through sweat, [18][19][20][21][22][23] and activity. [24,25] These demonstrations are steps toward future wearable multifunctional flexible electronic devices by further developing into a system with improved reliability.…”

Polyurethane foam coated with a multi-walled carbon nanotube/polyaniline nanocomposite for a skin-like stretchable array of multi-functional sensors

“…7 Beyond the conventional sensor that can detect a single stimulus, novel advanced sensors for simultaneous monitoring of multiple stimuli (multi-functional (MF) sensors) have been actively investigated. 8,9 For practical application of such MF sensors, it is necessary to eliminate the interference between different stimuli that is commonly observed in conventional MF sensors, 10 in addition to fabricating cost-effective sensors on a deformable substrate. Development of MF sensors that transduce different stimuli into separate signals can intrinsically minimize signal interference, thus allowing for sensitive detection of multiple parameters, such as temperature and pressure, in a single device without decoupling analysis.…”
