Flexinol Nitinol Actuator Wire(Shape-memory alloy)

A shape-memory alloy (SMA, smart metal, memory metal, memory alloy, muscle wire, smart alloy) is an alloy that “remembers” its original, cold-forged shape: returning the pre-deformed shape by heating. This material is a lightweight, solid-state alternative to conventional actuators such as hydraulic, pneumatic, and motor-based systems. Shape-memory alloys have applications in industries including medical and aerospace.

Piezo Film:

Piezoelectric Film is an enabling transducer technology with unique capabilities. Piezo Film produces voltage in proportion to compressive or tensile mechanical stress or strain, making it an ideal dynamic strain gage. It makes a highly reliable, low-cost vibration sensor, accelerometer or dynamic switch element. Piezo Film is also ideally suited for high fidelity transducers operating throughout the high audio (>1kHz) and ultrasonic (up to 100MHz) ranges.

inTouch by MIT Tangible Media Group

“inTouch” is a medium that enables users, who are separated from each other by distance, to communicate through touch. Specifically, force-feedback technology is employed to makes the users feel as if they are operating a shared physical object. The idea behind inTouch is to create the illusion that two people, separated by distance, are interacting with a shared physical object, developing the metaphor of a single physical object that exists in multiple places at once.

Tools & Technology1

Arduino:

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software.  It can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators.

XBee Shield:

The Xbee shield allows an Arduino board to communicate wirelessly using Zigbee.  It is based on the Xbee module from MaxStream.  The module can communicate up to 100 feet indoors or 300 feet outdoors (with line-of-sight).  It can be used as a serial/usb replacement or you can put it into a command mode and configure it for a variety of broadcast and mesh networking options.

Xbee Breakout Board:

This is a popular and simple breakout board for XBee, optimized for breadboard mounting and gateway applications, in other ways when you use it only as an interface. It can be directly connected to the FTDI cable or to a de-chipped Arduino board, the breakout board has all the components needed to interface with 5V boards, don’t forget that the XBee needs 3,3V.

There is also a detailed tutorial how to install and use the usb to serial converter and how to configure and test the XBee module, where you can set the XBee parameters which are also explained in details.

Patchube:

Pachube (“patch-bay”) connects people to devices, applications, and    the Internet of Things. As a web-based service built to manage the world’s real-time data, Pachube gives people the power to share, collaborate, and make use of information generated from the world around them.
