  • While a lot of tech companies have taken on the role of finding a way to expand on existing tools for personal safety, most of these devices are dependent on cell phones that makes these devices vulnerable and unreliable. Considering various difficult situations that a woman might face during an attack, this safety device had to be easily accessible no matter what physical and mental constraint the user may be in. On top of these usability aspects, making a feature-rich device small enough to camouflage with the daily outfits was a challenge.

  • In order to make woman safety device discreet, design mimics aesthetics of modern accessory. Device works with LoRaWAN (Long Range Wide Area Network) technology infrastructure provided by Tata Communications, avoiding any need to connect to a cell phone or cellular network. Oval-shaped and measuring less than two inches, device easily clips onto jeans pocket, t-shirt or sportswear. The device connects to nearest security services when user simply presses the SOS button thrice. Device also connects to a smaller trigger device via Bluetooth. So if main device is out of reach, users can also use trigger device to activate the signal.

  • Despite economic and technological developments, crime against women are increasing across the globe causing big social concerns. DEWI helps bring down these atrocities against women and help inducing a factor of safety amongst them. Sense of ownership of this product brings a level of confidence and comfort that the help is just a click away. While DEWI gives a woman independence she deserves, it also relieves their loved ones by allowing them keep a close check on them.
