“…Single crystalline silicon strain gauges on soft elastomer exhibit a linear relationship between strain and relative resistance changes with fast response times 21 . These sensors have been previously utilized to detect motion across various anatomical locations, such as the wrist 22 and fingers 23 . In addition, stretchable metal and single crystalline silicon temperature sensors 12,24 fabricated on ultrathin substrates have been applied for temperature monitoring on human skin.…”

Sensory receptors in human skin transmit a wealth of tactile and thermal signals from external environments to the brain. Despite advances in our understanding of mechano-and thermosensation, replication of these unique sensory characteristics in artificial skin and prosthetics remains challenging. Recent efforts to develop smart prosthetics, which exploit rigid and/or semi-flexible pressure, strain and temperature sensors, provide promising routes for sensor-laden bionic systems, but with limited stretchability, detection range and spatiotemporal resolution. Here we demonstrate smart prosthetic skin instrumented with ultrathin, single crystalline silicon nanoribbon strain, pressure and temperature sensor arrays as well as associated humidity sensors, electroresistive heaters and stretchable multi-electrode arrays for nerve stimulation. This collection of stretchable sensors and actuators facilitate highly localized mechanical and thermal skin-like perception in response to external stimuli, thus providing unique opportunities for emerging classes of prostheses and peripheral nervous system interface technologies.

“…In human-computer interaction (HCI) studies, sensor-based technologies have been the focus of research on gesture recognition (Benoit, Allevard, Ukegawa, & Sawada, 2003;Lyons, Brashear, Westeyn, Kim, & Starner, 2007), wearable devices for remote health monitoring (Patel. Park, Bonato, Chan, & Rodgers, 2012;Son et al, 2014), and smart home systems (Kühnel et al, 2011).…”

Abstract:Diverse aspects of our everyday lives increasingly feature sensor-based technologies. Despite the importance of understanding how business and consumers exploit and adopt these technologies, the information systems (IS) community has thus far devoted relatively little attention to the topic. Accordingly, in this paper, we foster an exploration of the issue among IS scholars by focusing on the emergent use of sensor-based technologies in the automotive insurance industry. Insurance providers have increasingly begun to turn to such technologies to gain competitive advantage around risk assessment and behavior-based pricing. To investigate this phenomenon, we consider the experiences of two organizations operating distinct national contexts: Progressive Insurance (US) and Generali (Italy). These two insurance providers have been first movers in adopting sensor-based technologies for risk assessment and policy pricing. First, we highlight the key similarities and differences between the cases with regard to the technologies adopted, business models pursued, and anticipated benefits and pitfalls for the companies and their consumers. Second, in a more holistic way, we discuss the implications and unintended consequences of sensorbased technologies in the automotive insurance industry. We formulate several research questions that provide opportunities and encourage more research in this emerging area of study.

“…In the mechanical method, the ultrathin devices are generally peeled off from the polydimethylsiloxane (PDMS) stamps or parylene release layer by mechanical forces 8, 20, 21, 22, 23, 24. While in the chemical method, the devices are released by dissolving different sacrificial layers like polyvinyl alcohol (PVA)25, 26 or polymethyl methacrylate (PMMA)27, 28, 29 with the corresponding solvents. To avoid the fragile properties of the ultrathin substrate during mechanical peeling and the potential hazards to the devices during chemical etching, an easy, integrated and ecofriendly device transfer method need to be used.…”

Organic field‐effect transistors (OFETs)‐based sensors have a great potential to be integrated with the next generation smart surgical tools for monitoring different real‐time signals during surgery. However, allowing ultraflexible OFETs to have compatibility with standard medical sterilization procedures remains challenging. A novel capsule‐like OFET structure is demonstrated by utilizing the fluoropolymer CYTOP to serve both encapsulation and peeling‐off enhancement purposes. By adapting a thermally stable organic semiconductor, 2,10‐diphenylbis[1]benzothieno[2,3‐d;2′,3′‐d′]naphtho[2,3‐b;6,7‐b′]dithiophene (DPh‐BBTNDT), these devices show excellent stability in their electrical performance after sterilizing under boiling water and 100 °C‐saturated steam for 30 min. The ultrathin thickness (630 nm) enables the device to have superb mechanical flexibility with smallest bending radius down to 1.5 µm, which is essential for application on the highly tortuous medical catheter inside the human body. By immobilizing anti‐human C‐reactive protein (CRP) (an inflammation biomarker) monoclonal antibody on an extended gate of the OFET, a sensitivity for detecting CRP antigen down to 1 µg mL−1 can be achieved. An ecofriendly water floatation method realized by employing the wettability difference between CYTOP and polyacrylonitrile (PAN) can be used to transfer the device on a ventricular catheter, which successfully distinguishes an inflammatory patient from a healthy one.
