“…The selection of power and speed, structural morphology and electrical and thermal characterization were described in detail in our previous work ( Srikanth et al., 2021 ). In brief, a polyimide sheet of 250 μm thickness was adhered to a glass substrate and a CO 2 laser of 10.6 μm wavelength was lased over the polyimide sheet to obtain laser induced graphene ( Kothuru et al., 2020 ). The parameters used for laser scribing are 4.5 W power in combination with a speed of 1.375 mm/s scanning speed.…”

“…As an example, Kothuru et al used LIG to manufacture flexible sensors for detection of H 2 O 2 at concentrations ranging between 1 μM and 10 μM. 59 To broaden the range of detection, H 2 O 2 -sensitive nanoparticles such as Pt NPs can be electrodeposited on the graphene generated by LIG on PI substrates (Figure 3D). 58 Similarly, a laser can be used to deposit metal structures on plastic substrates.…”

Hydrogen peroxide (H2O2) is a common chemical used in many industries and can be found in various biological environments, water, and air. Yet, H2O2 in a certain range of concentrations can be hazardous and toxic. Therefore, it is crucial to determine its concentration at different conditions for safety and diagnostic purposes. This review provides an insight about different types of sensors that have been developed for detection of H2O2. Their flexibility, stability, cost, detection limit, manufacturing, and challenges in their applications have been compared. More specifically the advantages and disadvantages of various flexible substrates that have been utilized for the design of H2O2 sensors were discussed. These substrates include carbonaceous substrates (e.g., reduced graphene oxide films, carbon cloth, carbon, and graphene fibers), polymeric substrates, paper, thin glass, and silicon wafers. Many of these substrates are often decorated with nanostructures composed of Pt, Au, Ag, MnO2, Fe3O4, or a conductive polymer to enhance the performance of sensors. The impact of these nanostructures on the sensing performance of resulting flexible H2O2 sensors has been reviewed in detail. In summary, the detection limits of these sensors are within the range of 100 nM–1 mM, which makes them potentially, but not necessarily, suitable for applications in health, food, and environmental monitoring. However, the required sample volume, cost, ease of manufacturing, and stability are often neglected compared to other detection parameters, which hinders sensors’ real-world application. Future perspectives on how to address some of the substrate limitations and examples of application-driven sensors are also discussed.

“…This work shows how to utilize UV laser manufacturing techniques for fabrication of stretchable multi-sensing arrays that address such issues for soft robotic and prosthetic applications. Although the elements of sensing network components -such as sensors [28][29][30] and conductive wires [31][32][33] fabricated by UV laser manufacturing -have been reported, the design of a multi-modal sensor network as reported here, including a combination of multiple flexible sensors and wire bundles on stretchable kirigami networks is new. It enables one to fabricate multiple sensors and wires on a 50 x 50 mm 2 sensor network, with a cost of $0.005 (USD) for metalized plastic film, in 3 minutes.…”

Soft robotic hands can facilitate human-robot interaction by allowing robots to grasp a wide range of objects safely and gently. However, their performance has been hampered by a lack of suitable sensing systems. We present a flexible and stretchable multi-modal sensor network integrated with a soft robotic hand. The design of wired sensors on a flexible metalized film was embodied through a manufacturing approach that uses both UV laser metal ablation and plastic cutting simultaneously to create sensor electrode patterns and stretchable conductive wires in a Kirigami pattern. Temperature and proximity sensors are combined into a single network. We evaluated the interconnects and sensors by measuring an impedance change to each external stimulus and showed that sensor readings are not substantially affected by stretching the network. With the sensor sheet wrapped around a soft robotic gripper, we demonstrated several interaction scenarios, including identifying hot and cold water bottles, a warm burrito for food handling, and a warm baby doll for future medical applications.
