The development of sensors for monitoring hazardous materials in security and environmental applications has been increasing in the last few years. In particular, organophosphates pose a serious health threat that affects the food and agriculture industries. Hence, their rapid on-site detection is highly desired, especially through remote robotic sampling that can minimize the exposure of humans to these hazardous chemicals. To handle sample collection, a robotic manipulator requires tactile feedback, to ensure that no damage will be done to either the robot or the other object in contact due to excessive force. To provide tactile feedback, porous polydimethylsiloxane pressure sensors based on a capacitive mechanism were chosen here, and integrated with enzyme-based electrochemical sensors specific for organophosphate compounds (e.g. methyl paraoxon). This results in a hybrid physical-chemical sensing glove that can simultaneously measure the pressure and chemical target without interference between the two sensors. Our pressure sensors showed 455% relative capacitance change per 10 kPa applied pressure, with an average sensitivity (S) of 0.057 AE 0.004 kPa À1 in the 3-20 kPa range and a maximum sensitivity of 0.30 AE 0.08 kPa À1 in the o0.05 kPa range. The chemical biosensors showed a detection range of 20-180 lM for methyl paraoxon in the liquid phase. We have thus combined low-cost chemical and pressure sensors together on disposable, retrofitting gloves, and demonstrated simultaneous tactile sensing and organophosphate pesticide detection in a point-of-use robotic field platform that is scalable, economical, and adaptable for different security, environmental, and food-safety applications.

Smart wearables, among immediate future IoT devices, are creating a huge and fast growing market that will encompass all of the next decade by merging the user with the Cloud in a easy and natural way. Biological fluids, such as sweat, tears, saliva and urine offer the possibility to access molecular-level dynamics of the body in a non-invasive way and in real time, disclosing a wide range of applications: from sports tracking to military enhancement, from healthcare to safety at work, from body hacking to augmented social interactions. The term Internet of Wearables (IoW) is coined here to describe IoT devices composed by flexible smart transducers conformed around the human body and able to communicate wirelessly. In addition the biochemical transducer, an IoW-ready sensor must include a paired electronic interface, which should implement specific stimulation/acquisition cycles while being extremely compact and drain power in the microwatts range. Development of an effective readout interface is a key element for the success of an IoW device and application. This review focuses on the latest efforts in the field of Complementary Metal–Oxide–Semiconductor (CMOS) interfaces for electrochemical sensors, and analyses them under the light of the challenges of the IoW: cost, portability, integrability and connectivity.

electronic devices built on planar substrates, textile electronic devices can be integrated into different materials that fit the curved surface of the human body or other nonplanar surfaces. Besides, it can bear deformations in almost all dimensions, making it applicable for long-term usage as minimal disruption can be made on the comfort and daily activities of the wearers. Another attractive feature of textile electronic devices is that, in principle, they are compatible to the conventional textile technology and can be manufactured on a large scale using the textile manufacturing technique, such as the rollto-roll process.Inspired by the exciting potential applications of textile electronic devices in healthcare, communications, environments, sports, security, and so on, in the past several years, many kinds of textile electronic devices have been produced by researchers all over the world, including sensors, solar cells, thermoelectric power generators and nanogenerators, diodes, transistors, circuits, etc. Ideally, these textile electronic devices would be directly woven into cloth and worn on human body for daily usage. As a result, these devices should be of lightweight, stable performance, and can bear deformations for long-term usage.Flexible textile electronic devices require flexible textile/fiber energy storage devices as compatible power suppliers. To match flexible textile electronic devices, the energy storage devices should have similar textile/fiber shapes with excellent flexibility, mechanical stability, light weight and can also bear deformations in all dimensions. Mainly two types of textile/fiber energy storage devices are explored including fiber lithium-ion batteries (LIBs) and fiber supercapacitors (SCs). [27][28][29][30][31][32][33][34][35][36][37][38][39][40] In recent years, LIBs were successfully made into fiber shapes to fit for flexible textile electronic devices. [41] Unfortunately, relatively complicated procedures are needed to fabricate fiber LIBs. Besides, the power densities of fiber LIBs are still quite low for practical applications. Compared with LIBs, supercapacitors offer higher power delivery capability, faster charge/discharge rates, long cycle livers, and bridging functions for the power-energy gap between traditions dielectric capacitors and batteries. These features make SCs ideal power suppliers for wearable and textile electronics.Over the past decades, researches on fiber SCs expanded very fast and great progresses have been achieved. Although several reviews focusing on some special aspects of fiber SCs Fiber supercapacitors (SCs), with their small size and weight, excellent flexibility and deformability, and high capacitance and power density, are recognized as one of the most robust power supplies available for wearable electronics. They can be woven into breathable textiles or integrated into different functional materials to fit curved surfaces for use in day-to-day life. A comprehensive review on recent important development and progress in fiber SCs is pro...
