Currently the number one campaign on Indiegogo, the Kite Patch is a patch that allows you "to go virtually undetected by mosquitos for up to 48 hours."
I have no idea what "virtually undetected" means or how effective this patch will be. The patch claims to work by using compounds that disrupt a mosquito's ability to detect human CO2 signatures.
Mosquitos love me, I still have giant welts all over my legs from my recent trip to Kauai, so if this works I will consider it a massive breakthrough. The campaign uses contributions to send Kite Patches to Africa to help to halt the spread of malaria, so I'm in with fingers crossed.
