Flexible optical sensors have been an emerging paradigm for applications in robotics, healthcare, and human–machine interfaces due to their high sensitivity, fast response, and anti-electromagnetic interference.
Recently, Marques reports a bioinspired multifunctional flexible optical sensor (BioMFOS), achieving a forces sensitivity of 13.28 μN, and a spatial resolution of 0.02 mm. The BioMFOS has a small dimension (around 2 cm) and a light weight (0.8 g), making it suitable for wearable application and clothing integration.
As proof-of-concept demonstrations, monitoring of finger position, trunk movements, and respiration rate are realized, implying their prominent applications in remote healthcare, intelligent robots, assistance devices teleoperation, and human-machine interfaces.
