If you're a very deep sleeper, you might need this vibrating alarm clock to wake you up. The Shakeawake is another cross-over product from the Royal National Institute for the Deaf (RNID), and clips to your pillow so it can lift you out of your slumber with a healthy dose of vibration. It takes batteries so you can take it in your travel bag, and also has an audible alarm for a double assault on your senses.
