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

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?

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.

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

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
