Computer "WISP" which can rewrite program without need of battery & wireless because it generates electricity using received radio waves

It is expected that everything is connected to the Internet by IoT, daily life is expected to change completely, but in the practical use of IoT terminal, the appearance of small and high capacity high performance battery is awaited. However, if you do not need a battery in the first place, you do not have to worry about running out of the battery, so when receiving radio waves energy is generated and a compact computer that can drive with no battery required "WISP"Has been developed by researchers at the University of Washington.

This is a computer "WISP" which can be used without a battery, such as the antenna like the antenna that researcher Presley Slow · Paul Kuzak holds.


WISP is a computer that can drive by changing the received radio waves to energy, and can be used without a battery. Since there is no battery, of course, charging is not necessary.


Although it is WISP which runs without batteries, until now, it was necessary to connect with the PC using a cable to rewrite the program.


This time the researchers succeeded in rewriting the WISP program wirelessly. In other words, WISP can rewrite programs wirelessly without the need for batteries & cables, so it has become a terminal that can be driven semipermanently by updating programs as appropriate.


In addition to not requiring a battery, WISP which can rewrite programs wirelessly is infinitely useful in IoT.


WISP is a small battery-less computer developed by researchers at the University of Washington sensor laboratory, the bandwidth is equivalent to Bluetooth LE and the computing performance realizes wearable terminal Fitbit level, mainly measuring sensor information continuously It is assumed to be used in such applications.


Although it is still WISP in the early stage of development, it has already succeeded in reading sensor information without a battery, and this time it seems that the wireless reprogram from the remote has succeeded. By implementing batteryless & wireless program updating, WISP can be utilized as an example of a wearable terminal for fitness that tracks and transmits the user's health condition, a sensor terminal that detects and transmits the state of a structure such as a bridge girder on a highway It is being considered to apply to such as. Terminals like WISP that can update the program remotely without the need for a battery, it seems that various IoT terminals are expected to appear in the future.
