Sensing and sensors Sensing: technique to gather information about physical objects or areas Sensor(transducer): object performing a sensing task; converting one form of energy in the physical world into electrical energy Examples of sensors from biology: the human body eyes: capture optical information(light) ears: capture acoustic information(sound) nose: captures olfactory information(smell) skin: captures tactile information(shape, textureSensing and Sensors • Sensing: technique to gather information about physical objects or areas • Sensor (transducer): object performing a sensing task; converting one form of energy in the physical world into electrical energy • Examples of sensors from biology: the human body • eyes: capture optical information (light) • ears: capture acoustic information (sound) • nose: captures olfactory information (smell) • skin: captures tactile information (shape, texture)
