“…The ability to develop flexible piezoresistive sensors additively proved useful in several areas. A few examples of applications are wearable electronics [ 51 ], airflow sensors [ 170 ], food monitoring [ 171 ], embedded pressure sensors in tires [ 172 ], and pneumatic actuators [ 173 ]. A 3D-printed flexible piezoresistive pressure sensor was developed by Fekiri et al using polydimethylsiloxane and multi-walled carbon nanotubes (MWCNT-PDMS composite) and direct ink write AM ( Figure 21 ) [ 174 ].…”

Embedded sensors (ESs) are used in smart materials to enable continuous and permanent measurements of their structural integrity, while sensing technology involves developing sensors, sensory systems, or smart materials that monitor a wide range of properties of materials. Incorporating 3D-printed sensors into hosting structures has grown in popularity because of improved assembly processes, reduced system complexity, and lower fabrication costs. 3D-printed sensors can be embedded into structures and attached to surfaces through two methods: attaching to surfaces or embedding in 3D-printed sensors. We discussed various additive manufacturing techniques for fabricating sensors in this review. We also discussed the many strategies for manufacturing sensors using additive manufacturing, as well as how sensors are integrated into the manufacturing process. The review also explained the fundamental mechanisms used in sensors and their applications. The study demonstrated that embedded 3D printing sensors facilitate the development of additive sensor materials for smart goods and the Internet of Things.

We propose distance-based distributed adaptive formation control of point mass agents in port-Hamiltonian (pH) framework that can deal with parameter uncertainties and with mixed dimensional space (2D, 3D or mixed 2D/3D). Adaptive control mechanism is subsequently proposed to maintain formation of uncertain pH systems with unknown damping parameters. Numerical simulations are presented for both known and uncertain point mass agents in mixed 2D/3D space.

“…The details of the design and fabrication of the GNP‐based cantilever sensor and its high gauge factor and stable piezoresistive behavior as measured in the past work. [ 20 , 48 , 49 , 50 ] To eliminate errors and uncertainty arising out of sensor‐to‐sensor variability, the same cantilever sensor was used for all the tests, and the whisker‐sensor assembly was designed in a way that the whisker to be tested could be easily mounted and dismounted from the cantilever sensor's free end (Figure 6a–c ), thus ensuring a fair comparison between the VIV responses across the varying λ / D m ratios.…”

Seals are well‐known for their remarkable hydrodynamic trail‐following capabilities made possible by undulating flow‐sensing whiskers that enable the seals to detect fish swimming as far as 180 m away. In this work, the form‐function relationship in the undulating whiskers of two different phocid seal species, viz. harbor and gray seals, is studied. The geometry and material properties of excised harbor and grey seal whiskers are systematically characterized using blue light 3D scanning, optical and scanning electron microscopy, and nanoindentation. The effect of the undulating geometry on the whiskers’ vibration in uniform water flow is studied using both experimental (piezoelectric MEMS and 3D‐printed piezoresistive sensors developed in‐house) and numerical (finite element method) techniques. The results indicate that the dimensionless ratio of undulation wavelength to mean whisker diameter (λ/Dm) in phocid seals may have evolved to be in the optimal range of 4.4–4.6, enabling an order‐of‐magnitude reduction in vortex‐induced vibrations (compared to a similarly‐shaped circular cylinder) and, consequently, an enhanced flow sensing capability with minimal self‐induced noise. The results highlight the importance of the dimensionless λ/Dm ratio in the biomimetic design of seal whisker‐inspired vibration‐resistant structures, such as marine risers and wake detection sensors for submarines.
