A Fabric-Based Sensing System for Recognizing Social Touch
A Fabric-Based Sensing System for Recognizing Social Touch

Burns, R. B., Lee, H., Seifi, H., Kuchenbecker, K. J.

Work-in-progress paper (3 pages) to be presented at the IEEE Haptics Symposium, Washington, DC, USA, March 2020 (misc) Accepted

Abstract
We present a fabric-based piezoresistive tactile sensor system designed to detect social touch gestures on a robot. The unique sensor design utilizes three layers of low-conductivity fabric sewn together on alternating edges to form an accordion pattern and secured between two outer high-conductivity layers. This five-layer design demonstrates a greater resistance range and better low-force sensitivity than previous designs that use one layer of low-conductivity fabric with or without a plastic mesh layer. An individual sensor from our system can presently identify six different communication gestures – squeezing, patting, scratching, poking, hand resting without movement, and no touch – with an average accuracy of 90%. A layer of foam can be added beneath the sensor to make a rigid robot more appealing for humans to touch without inhibiting the system’s ability to register social touch gestures.

Preparation of high-efficiency nanostructures of crystalline silicon at low temperatures, as catalyzed by metals: The decisive role of interface thermodynamics

Wang, Zumin, Jeurgens, Lars P. H., Mittemeijer, Eric J.

2011 (mpi_year_book)

Abstract
Metals may help to convert semiconductors from a disordered (amorphous) to an ordered (crystalline) form at low temperatures. A general, quantitative model description has been developed on the basis of interface thermodynamics, which provides fundamental understanding of such so-called metal-induced crystallization (MIC) of amorphous semiconductors. This fundamental understanding can allow the low-temperature (< 200 ºC) manufacturing of high-efficiency solar cells and crystalline-Si-based nanostructures on cheap and flexible substrates such as glasses, plastics and possibly even papers.

The sweet coat of living cells – from supramolecular organization and dynamics to biological function

Richter, Ralf

2011 (mpi_year_book)

Abstract
Many biological cells endow themselves with a sugar-rich coat that plays a key role in the protection of the cell and in structuring and communicating with its environment. An outstanding property of these pericellular coats is their dynamic self-organization into strongly hydrated and gel-like meshworks. Tailor-made model systems that are constructed from the molecular building blocks of pericellular coats can help to understand how the coats function.
