The E-Taster-Assistance System with Multi-Spectral Lab-on-Spoon/-Fork as 'Electronic Tongues' for Nutritional Comfort Functions,

Sustainable Food Use, and Food Safety

Outline of the talk: Motivation E-Taster Assistance System Multi-Spectral Lab-on-Spoon/-Fork Experiments & Results Conclusions


Motivation

Smart Homes find widespread interest to improve comfort, energy

efficiency, safety, sustainability, & AAL Relevant subtask Smart-Kitchen requires qualitative & quantitative

assessment of food quality and food safety (food adulteration !)

Obstacles: lack of experience, acquired perception deficiency (age/injury) or assessment beyond human abilities

Assistance system for restored/ augmented sensing

´´Electronic Tongues´´ in Spoon/-Fork guise as front-ends

LoS V1 from 2014

Multi-Spectral Lab-on-Spoon/-Fork ArchitectureAutonomous/Self-Sufficient Wireless Integrated Multi-Sensor System

Multi-Sensor-System: Multi-Color/NIR Spectroscopy, Impedance Spectroscopy, Temperature context

Low-cost and -power solution, AFE, Arduino ProMini,USB/XBee

Accumulator with charging circuit for autonomous operation


Multi-Spectral Lab-on-SpoonFirst Unsealed Prototype (Arduino pro mini) with USB-Host Communication

Multi-Sensor-System: Multi-Color/NIR, Impedance Spectroscopy, T pH, viscosity, IR, … in preparation

Integrated/Embedded low-power solution employing 3D-Packaging

Helps to scale, identify, and grade (fresh, rotten, contaminated, ...) food by elaborated Computational Intelligence approach

Extension to energy scavenging (Solar cell, vibration, ...)


Multi-Spectral Lab-on-ForkSealed Prototype with Identical Architecture and Information Processing

Lab-on-Fork was conceived for this, changing the optical/NIR spec-troscopy from transmitted/scattered to reflected light measurement

Lab-on-Spoon is fine for liquid food/ingredients But solid food, e.g., meat, fish, vegetables, or fruit,

and granular/ powdery food, e.g. tea, coffee, or spices, have to be checked, too

Conclusions

E-Taster system for evaluating sensory fingerprints of food samples by low-cost LoX device suitable for mass-market

Application: AAL, Adulteration, Sustainability, Nutritional Comfort Focus: Retail-to-Fork

Sensory extension, e.g., UV for fluorescence Advanced (foodsafe) packaging, e.g., metal sintering Develop a comprehensive fingerprint database of food ingredients
