The electronic pen will vibrate to signal an illegible letter or misspelled word. The pen will function in either calligraphy mode (vibrating when a letter is written incorrectly) or orthography mode (vibrating to signal a spelling or grammar error). Future generations of the pen will include pressure sensors and a network module to transfer data 'written' with the pen to digital devices.

A new handheld food scanner paired with a smartphone will let users quickly identify the ingredients in their foods, making it easier to avoid allergens, chemicals or unwanted additives. Designed to allow users to make smarter food choices, the device will use a Raman spectrometer, specialized cloud-based algorithm and a smartphone app. Beaming the low-powered laser at the food product in question will cause the food to emit low energy protons, which will then be sorted by...

The wristband will help keep track of your emotional health, monitoring your mood and offering suggestions if you seem a bit unbalanced. The wristband will contain the "life spectrum analyzer", which is a medical-grade. Rather than simply gathering data on heart rate or blood pressure, the device will monitor the body's entire autonomic nervous system by capturing and analyzing the electrical impulses from the cells in the right atrium. The results will then be sent to the user's...

It will be possible to keep track of salt intake with the handy salt meter, a sort of salt-content thermometer for hot, liquid foods. The device will designed primarily for aficionados of salt-prone soups like ramen or udon noodles. It can be inserted into any semi-liquid food with a temperature between 140 and 176 degrees F, and the results will be displayed in less than a second on the LED screen. A bit of math will be required to come to the final reading, with a reading of 1...

Singing in the shower will get a bit easier with a shower head featuring an integrated wireless, waterproof speaker. The shower head speaker will communicate with any Wi-Fi enabled music player up to 39 feet away. The speaker will be magnetically attached to the shower head, and will be easily removed for recharging or for use at other, potentially damp places. The shower head will be powered by a lithium-ion battery, which can last up to seven hours and will be recharged by the...

Designed with diabetic children in mind, the pen will be the first insulin device able to deliver insulin in half-doses. The pen will be styled for children to use, who typically require only a half-dose of insulin. It will feature a dial to choose the insulin dose and a memory function, which will show the time of each previous injection so parents will be sure their children are administering their insulin properly.

Do not try to warm the frostbitten area with hot water. You can use only water with a temperature of no more than 107 °F. If frostbitten area starts to hurt, do not be shy and see a doctor!

A new kind of bed linens uses a "dot matrix" design to help reduce the risk of bed sores in bed-ridden patients. The linen's unique, woven design creates less surface contact with the skin and has fewer contact points than traditional linens. The gaps between the "dots" also make the material more absorbent. The linens reduce sweat and improve blood circulation, resulting in greater patient comfort.

A new smart sock for infants will track the baby's sleeping position and other vitals, allowing nervous parents to get a bit more sleep at night. The sock will be equipped with an array of sensors able to monitor the baby's heart rate, temperature, oxygen levels and sleep position. The data will be sent via Bluetooth to the parent's smartphone, allowing them to keep tabs on their baby without needing to go into the room every few minutes (which is common for new parents). In...

A new contraceptive made of electrically spun nanofiber will dissolve in the woman's body, protecting her from both pregnancy and sexually transmitted diseases. The contraceptive will developed by electrospinning, which will create fibers from liquid in an electric field. The dissolved polymers and antiretrovirals will be manipulated to control shape, strength and solubility, and adhere to a collecting plate once they are formed. This will create a stretchy material that can...
