Sensors are the next wave in personal tech. We already have heart-rate sensors, organic produce sensors, even laundry sensors. Matt Rogers, the tech whiz behind the Nest thermostat, surveys five gadgets on the bleeding edge.
Basis band [1] Basis tracks your heart by way of your wrist: LEDs shine through capillaries, reflecting light back to an optical sensor that measures blood flow and pulse rate, minus the bothersome chest straps. ($200, mybasis.com)
ROGERS SAYS: Basis stands out, thanks to “deeper insights into fitness” through sensors for sweat levels and skin temperature.
Lapka [2] The original Geiger counter (an air particle detector for radiation levels) gets a refresh in the Lapka. The quartet of devices measure electromagnetic fields, radiation, humidity, and organic content of food. ($220, mylapka.com)
