“…Posture and dynamic body activities of athletes have been monitored using MEMS-based sensors. The body positioning of swimmers at different stages was visualized using MEMS-based pressure sensors (Bottoni et al , 2011). MEMS-based shape sensors are earmarked for their application and can perform in workplaces where strain and optoelectronic sensors cannot be installed.…”

Purpose This paper aims to review the shape sensing techniques using large area flexible electronics (LAFE). Shape perception of humanoid robots using tactile data is mainly focused. Design/methodology/approach Research papers on different shape sensing methodologies of objects with large area, published in the past 15 years, are reviewed with emphasis on contact-based shape sensors. Fiber optics based shape sensing methodology is discussed for comparison purpose. Findings LAFE-based shape sensors of humanoid robots incorporating advanced computational data handling techniques such as neural networks and machine learning (ML) algorithms are observed to give results with best resolution in 3D shape reconstruction. Research limitations/implications The literature review is limited to shape sensing application either two- or three-dimensional (3D) LAFE. Optical shape sensing is briefly discussed which is widely used for small area. Optical scanners provide the best 3D shape reconstruction in the noncontact-based shape sensing; here this paper focuses only on contact-based shape sensing. Practical implications Contact-based shape sensing using polymer nanocomposites is a very economical solution as compared to optical 3D scanners. Although optical 3D scanners can provide a high resolution and fast scan of the 3D shape of the object, they require line of sight and complex image reconstruction algorithms. Using LAFE larger objects can be scanned with ML and basic electronic circuitory, which reduces the price hugely. Social implications LAFE can be used as a wearable sensor to monitor critical biological parameters. They can be used to detect shape of large body parts and aid in designing prosthetic devices. Tactile sensing in humanoid robots is accomplished by electronic skin of the robot which is a prime example of human–machine interface at workplace. Originality/value This paper reviews a unique feature of LAFE in shape sensing of large area objects. It provides insights from mechanical, electrical, hardware and software perspective in the sensor design. The most suitable approach for large object shape sensing using LAFE is also suggested.

“…Human activity recognition measured by IMUs is applied to several fields of medicine [20,21], rehabilitation [22], robotics for exoskeleton-based patient training [23,24] and sport [25]. Concerning this last field in further detail, applications involve tennis [26], football [27,28], swimming [29][30][31][32][33], basketball [34], cycling [35], skiing [8,9], martial arts [36] and running [37]. Interactive solutions have been introduced [30] which are able to represent in real time the 3D spatial positioning of the body in sport activities in order to evaluate the posture and kinematics of athletes.…”

The relevance of wearable sensing systems has increased in recent years, particularly in medicine and sport. In these fields, the main benefit of non-invasive and comfortable wearable devices is the real time evaluation of a patient's physiological conditions. Body monitoring is generally based on the measurement of heart rate, heart rate variability, body motion, breath, skin temperature and metabolic parameters (electrolytes, lactic acid, pH, etc). The basic requirements of wearable systems are lightness, flexibility, reliability and low power consumption. In addition, wearable sensors must provide acceptable levels of accuracy, repeatability and noise. Different solutions have been proposed to develop sensors specifically for wearable systems. The evolution of materials, the reduction of power consumption and the development of fiber treatments have supported the prototyping of integrated wearable sensing systems. The goal of this review is to provide a general description of the technologies relating to wearable sensors that have been adopted in medicine and sport, and to review device typologies, sensing strategies and future perspectives.

“…Another interesting solution was proposed by Bottoni et al , who used wearable mini paddles provided with MEMS pressure sensors to monitor technical skill differences in swimmers. The authors found that each athlete showed a distinctive shape of the pressure curve, but triathlon swimmers showed a greater variability in the pressure pattern than top level swimmers [ 105 ]. Pressure sensors were also recently mounted on the shoulders of front row rugby players, to measure the mechanical loads on professional players of 11 elite rugby teams, when they adopted different strategies during scrummaging.…”

Over the past few decades the increased level of public awareness concerning healthcare, physical activities, safety and environmental sensing has created an emerging need for smart sensor technologies and monitoring devices able to sense, classify, and provide feedbacks to users’ health status and physical activities, as well as to evaluate environmental and safety conditions in a pervasive, accurate and reliable fashion. Monitoring and precisely quantifying users’ physical activity with inertial measurement unit-based devices, for instance, has also proven to be important in health management of patients affected by chronic diseases, e.g., Parkinson’s disease, many of which are becoming highly prevalent in Italy and in the Western world. This review paper will focus on MEMS sensor technologies developed in Italy in the last three years describing research achievements for healthcare and physical activity, safety and environmental sensing, in addition to smart systems integration. Innovative and smart integrated solutions for sensing devices, pursued and implemented in Italian research centres, will be highlighted, together with specific applications of such technologies. Finally, the paper will depict the future perspective of sensor technologies and corresponding exploitation opportunities, again with a specific focus on Italy.
