(5) POPSCI CONCEPT: Inspired by high-tech toothbrushes like the Sonicare Elite 7500 ($140; sonicare.com), we envisioned the Sensabrush, a toothbrush that not only promotes oral hygiene but tests for it as well. Electrodes embedded in the brush head check for abnormally high levels of the bacteria that can cause anything from bad breath to gum disease.From top: courtesy Neorest; courtesy Hansgrohe; courtesy Tanita; courtesy Treadclimber; illustration by Kenn Brown and Chris Wren

Tomorrow's personal-care space may well be the most connected room in the house, with sensors ready to analyze nearly everything you do. Many products will appear in Europe and Asia before you see them in the U.S. Here we show a few of the many goodies available now, and predict where they will evolve in 5 to 10 years.

TOILETS

Today: Toto's Neorest 600 toilet (1) ($5,000; totousa.com) uses sensors to determine how much to raise or lower the seat and how much water the flush needs. It will clean and dry you when you're done. Its WellYou2 model, available in Japan, measures urine sugar, then sends the data to your doctor.

Tomorrow: The toilet will also do other medical tests, such as check for blood or abnormal bacteria in the urine or stool. It might even indicate if a woman is pregnant.

BATHING

Today: Hansgrohe's Pharo Prestige Sensotronic Panel SL 20 (2) ($3,500; hansgrohe-usa.com) includes a regular showerhead, a hand shower and six adjustable sprays coming from the body of the panel. You can redirect water to any of these jets using the shower's digital control panel, which also displays and regulates water temperature. A valve in the panel monitors temperature and pressure in the shower's supply lines, continually adjusting flow to prevent unwanted bursts of hot or cold water.

Tomorrow: Expect showers with automatic drying units, so there will be no need for towels, along with self-cleaning bathtubs.

HEALTH MONITORS

Today: Tanita's BF592 scale (3) ($100; www.tanita.com) both calculates your body-fat percentage and checks your hydration level. After you calibrate the scale by entering information such as your age, weight and sex, the scale sends a small electrical current from foot to foot. Based on your body's resistance to the current, the scale determines both your body's hydration level and body-fat percentage.

Tomorrow: A ring attached to the scale could track your temperature, heart rate and blood oxygen, then send your data to your doctor.

FITNESS EQUIPMENT

Today: TreadClimber's TC5000 (4) ($2,200; treadclimber.com) includes two parallel treadmills, one for each foot, that also move up and down like a stepper. Its electronics monitor everything that gym machines do, including speed, time, distance, calories burned, calories per minute, and total steps.

Tomorrow: Your home gym equipment will track your workout and feed the data to a Web site. When you visit the hotel gym while traveling, the equipment will download your regular routine, then recommend sets and weights based on your fitness level and the exercises you do at home.
