“…We found that with increasing iteration count, the load curve converges to the unload curve. This is also validated in the long-term behavior described in detail later and can be explained by an increasingly better intertwinement of the fibers in the sensor fabric with an increased number of trials and the material creep in the fabric as explained in [19]. Second we evaluated the response of the sensor using 3 and 5 cm 2 circular flat probe tips in addition to the 1 cm 2 tip (Fig.…”

h i g h l i g h t s• A flexible and stretchable durable fabric-based tactile sensor capable of capturing typical human interaction forces was developed.• We present elaborate measurement results of the sensor. • A process of creating multiple sensor areas in a single fabric patch was developed.• The measures against performance degradation due to moisture are presented. • Using the developed technology, a tactile dataglove with 54 pressure sensitive regions was built.a r t i c l e i n f o Article history: Available online xxxx Keywords: Tactile sensor Flexible tactile sensor Stretchable tactile sensor Tactile dataglove a b s t r a c tWe introduce a novel, fabric-based, flexible, and stretchable tactile sensor, which is capable of seamlessly covering natural shapes. As humans and robots have curved body parts that move with respect to each other, the practical usage of traditional rigid tactile sensor arrays is limited. Rather, a flexible tactile skin is required. Our design allows for several tactile cells to be embedded in a single sensor patch. It can have an arbitrary perimeter and can cover free-form surfaces. In this article we discuss the construction of the sensor and evaluate its performance. Our flexible tactile sensor remains operational on top of soft padding such as a gel cushion, enabling the construction of a human-like soft tactile skin. The sensor allows pressure measurements to be read from a subtle less than 1 kPa up to high pressures of more than 500 kPa, which easily covers the common range for everyday human manual interactions. Due to a layered construction, the sensor is very robust and can withstand normal forces multiple magnitudes higher than what could be achieved by a human without sustaining damage.As an exciting application for the sensor, we describe the construction of a wearable tactile dataglove with 54 tactile cells and embedded data acquisition electronics. We also discuss the necessary implementation details to maintain long term sensor performance in the presence of moisture.

“…In the second reservoir the water replaces the air which is then passing the thermal flow sensor for measurement. The water volume's equivalent mass leaving the first reservoir is measured by a scale (Sartorius DP 225 D) which then can be converted into an air flow by the continuity equation [27,26]. Tables 3 and 4 specify the resulting minimum flow rates for the channel ( Q in mm 3 /s) and flow velocities ( u in mm/s) as well as the sensitivities for different sensor types.…”

“…This is a result of optical interference, which is significant for film thicknesses that are similar to the optical wavelength. 9 Typical lamps have a coherence length of many micrometers 9,10 and a large number of reflections forth and back must hence be considered; see for example the text book by Born & Wolf. Obtaining the complex refractive indexn (λ) = n (λ) (1 + iκ (λ)) from thin-film measurements is nontrivial.…”

We report on an optical transmission spectrometer optimized for tiny samples. The setup is based on all-reflective parabolic optics and delivers broadband operation from 215 to 1030 nm. A fiber-coupled light source is used for illumination and a fiber-coupled miniature spectrometer for detection. The diameter of the probed area is less than 200 μm for all wavelengths. We demonstrate the capability to record transmission, absorption, reflection, fluorescence and refractive indices of tiny and ultrathin sample flakes with this versatile device. The performance is validated with a solid state wavelength standard and with dye solutions.
