Transcript and Presenter's Notes

Title: Sensors


1
Sensors
  • Almost anything can be measured
  • Model of the system
  • Intelligence
  • Flower-pot sensor
  • humidity
  • temperature
  • light
  • request for attention

2
Actuation
  • Information processing is easy
  • alarms, entertainment, communication, etc.
  • Simple electric control
  • Mechanical systems are difficult
  • Robotics

3
Smart clothing and wearable technology
4
What are wearable technology and smart clothing?
  • Convergence products of Textile and ICT
    industries
  • How to
  • improve the functions of a garment?
  • bring new functions to a garment?
  • design the garment so that it can incorporate
    electronics?
  • design electronics that is embedded into a
    garment?
  • technology is used?

6
Wearable technology
  • Gadgets that have no use unless worn
  • Typically information processing, sensors,
    displays, communication
  • Context dependent data, time, place, user
  • Heart beat monitor, health monitors, medical
    measurement devices, etc.

7
Swimmers distancemeter
  • Clothing swimmers distance meter
  • Typical design
  • cheap sensors
  • novel signal processing algorithms
  • implementation on a micro controller
  • small display, few buttons
  • injection molded enclosure
  • Calculates the direction of movement of a swimmer
    using magnetic sensors and signal processing
  • Good results, commercial product
  • 2 MSc. thesis algorithms and HW

8
Smart clothing
  • Clothing with enhanced functionality
  • Enhanced basic functions
  • protection
  • looks
  • pockets
  • Additional functions
  • communication
  • measurements
  • etc.

9
Electrically heated clothing
Please, dont laugh.
  • Technologies Enabling Smart Clothing - project
  • Research on usability of electric heating in
    garments
  • usability
  • technologies
  • energy balance
  • effect on sweating
  • measures
  • temperature
  • humidity
  • power consumption
  • controls heating

10
Intelligent textiles
  • Functional textile materials, smart materials
  • No (electronic) information processing
  • Phase change materials, color changing materials,
    micro porous matarials, bioactive materials
  • Use also as components for
  • sensors
  • actuators
  • information transfer, wires, antennas

11
Wearable user interfaces
  • Information appliance can be used as a user
    interface to a wearable system
  • Includes a display, keyboard, local communication
    link
  • Often has a internet communication link
  • Programmable
  • Resources in the appliance
  • Tools available
  • People available
  • E.g. as an interface to medical sensors embedded
    into clothing

12
Promising field of application
  • Promising field of application for smart clothing
    and wearable technology is
  • Physiological measurements
  • Medical applications
  • Elderly care
  • Sports
  • Health and fitness

13
Placement of sensors
  • Smart clothing is an exellent place to put
    sensors
  • Application and context dependent data
  • User interfaces / autonomic measurements
